My system:

Intel motherboard
Pentium D
PVR-250
SATA drives
Gigabyte 6600GT
latest Knoppmyth install Rev C. (R5C7?)

I am using the PVR-250 to record from the svideo input. I can watch live TV, program guide works fine. My svideo input is from a Dish network box. I only have a single channel on my DISH netowrk box. No external tuning necessary. I can record the current live TV show in the live TV MythTV screen. It records and creates a file. I can later select and play that live TV file from watch recordings. However if I set up a recording via the program guide which is some time in the future, everything seems to fire up to record, but when I go to select the recorded file in Watch Recordings", I get an error of:

File for this recording can not be found

Not sure where to start for solving this problem. I did a few google and forum searches but I did not find anything specific.

The backend log would be the place to start investigating. Check out the wiki for article on the logs and troubleshooting.

Hi,
I would suspect this is not a hardware problem. Based on what I think I understand from your post, You don't get a recording from an alternative path.

If you record using the tuner (assuming an antenna / cable) it is ok?
If you record from Dish (assuming composite /svhs from external) is bad?

Again, assuming that however you get the Dish into your KM machine, it is viewable?

For an example, I have a vcr / camera / external video source going into the composite RCA connector which I have designated to be channel 1 with an id of Video (creative huh?) When I select channel 1, I can view fine, pressing R will not record because there is no EPG entry. I can manually program to record channel 1 from time x to time y and it works properly.

Is this the direction of your issue?

I live in a far out area and can not receive much from an antenna. So:



I do not have a connection to the PVR-250 tuner. Not much to receive via an antenna. So the answer is I do not know.



It seems to be fine in Live TV. This is all I am using. DISH box svideo OUT to PVR-250 svideo IN. I only get one channel on the DISH box. So there is no tuning necessary of the DISH box. However the one channel I get is DISH channel number 610. This information appears fine in the program guide. I can see this svideo input fine in Live TV. I can record Live TV just fine from the Live TV screen.



Yes.

I have not yet checked all my log files. I did look a "messages" log file and saw no errors reported in that file. At least none that I recognized as an ERROR. I will post anything I find this evening in other log files.

So my probelm is that I can not select a program to record from the program guide screen and actually have it record a file. I can record a file while in Live TV. Both operations create various entries in MythTV but the files started by using the program guide result in 0 length and the above mentioned error - "The file for this recording can not be found".

Make sure that you don't have two sets of channels. i.e. make sure that all the channels that you have defined, actually exists and are good. Otherwise, the scheduler may be recording on bad channels. ex: if you had two NBC channels, one via SAT and one OTA, it may be picking the bad one to record on.

I had trouble where new channels would appear in my area, from stations going digital in neighboring cities. Zap2It would then add them to my lineup, and sure enough, the scheduler would want to use those for recording, instead of the ones that I actually could receive. I'd get zero length recordings for those. Take a look at the /myth/tv directory and you'll see the files.

Just so it is clear, I have only one channel from DISH network that I do anything with in the program guide. 1 channel. I only have one input on the PVR-250, the svideo input, that I configured.



So, I only have one set of channels. Mythtv has a problem with a ZAP list that has a single channel in it. So, I added 3 other valid DISH channels to my lineup. BUT, I only select from the guide the ONE channel I get from DISH. It truely is a very simple thing I am doing in Mythtv. There is NO external tuning of the DISH network box, I have no way to do this and no need to do this. I only use the svideo input of the PVR-250 and is the ONLY input I defined in mythtv-setup.

I am off the check the logs....

After reading my mythbackend.log file I saw:

Changing from None to WatchingLiveTv
GetCurrentChannelNum(610): Error, failed to find channel '610'
Channel(/dev/video0)::TuneTo(610): Error, failed to find channel
TVRec (1) Error: Failed to set channel to 610. REverting to KState_None
TVRec(1) Change from RecordingOnly to None

This listing is similar in this thread:

http://mysettopbox.tv/phpBB2/viewtopic.php?t=10384&highlight=getcurrentchannelnum

But it really did not indicate to me how I go about solving it.

This is another similar problem:

This is an intersting statement. Since, I am not using the tuner0 input of the PVR-250 so I never set this up. I only setup the svideo0 input. So, I am not sure if this should be done in my case. I have erased and resetup everything in myth-setup several times. BUT, I only ever setup the svideo0 input of the card.



Yep. This is done for me by the new mythtv-setup. Any channel id is copied into the frequency id of the second page of the setup.



Whew....not sure I can tackle #2 above. Do I really need to do this? My concern is the steps to edit the database. Is this truely the solution?

Hi scrowner,

Ok on the ONE single uno channel I thought things were tough when I was kid and we only got two channels (b/w them days

I still think it is settings. As an idea, pretend that you have a hundred channels available on the Dish and that you would like to be able to control them from your favorite eazy chair. How would you set it up? A pretend IR blaster of course. I don't know exactly how that is done, however a careful scan of the forum should bring up a plan and don't forget the wiki!

Basicly, you setup external control and the card is "locked" to an input. Once it is locked into place it knows the EPG info is to be used to change the external device. Because the EPG info is correct and the tuner card is locked because of external all is happy and you should be good to record using all normal modes, manual, R, or scheduling.

You may have to dump the setup data and start fresh.

That is about all I can offer. I would think a Dish would have more than one channel?

Have a great day!
Mike

This whole mythtv thing seems very much still in its infancy. It has been a struggle. But thank goodness for this knoppmyth forum.



As I said, I have done that several times. In reference to the comments about my silly setup, how about getting down to my questions? My setup is by design. I have Directtv for my TV/recording needs. I have DISH network for my wife's homeland language. Dish provides tailored channel lineups and there is ONE in my wifes language - Tamil. So, She asked to record her movies and place them onto DVD. I obliged with Mythtv. Yep, ONE stinking channel, and that is all I need.




How does one go about implementing this, assuming this is a solution to my PROBLEM and not a change to my setup to allow DISH channel changing? I only have one channel on the DISH network box.

For those looking for an answer....Mythttv has a bunch of bugs. With a little playing around I may have a solution to:

"File for this recording not found."

But like everything in the Mythtv environment it MAY only apply to my particular hardware and setup. So what I did is:

1. I exited mythtv.
2. I went to a terminal program and entered as su.
3. Entered: /etc/init.d/mythtv-backend stop
4. Entered: mythtv-setup
5. I went to Channel Editor and selected the channel I am having problems with , in my case 610.
6. I went to the next screen of the channels options. This has an entry for Frequency/Channel.
7. This defaults to my channel, 610. So I tried clearing the entry.
8. Exit out of the setup and reboot.
9. Mythtv still did not record from the program guide and the errors entered in mythtvbackend.log indicated, getcurrentchannelnum() - no channel number now instead of 610.
10. I did steps 1-6 above.
11. I entered 4 into the frequency/channel field. Why you ask? because I had read it from mjl! in[url]
http://mysettopbox.tv/phpBB2/viewtopic. ... channelnum[/url]
12. I exited out ot the mythtv-setup and rebooted.
13. BINGO....I could record from my program guide when selecting programs from channel 610.

I suspect any channel configured to svideo0 input should be changed to 4? I do not know. Additionally, when looking at the mythtvbacken.log I now see:

TVRec(1): Changing from None to RecordingOnly
Started recording: .............
scheduler: Started recording.........
Commercial Flagging started.........

So no errors in the LOG. Yeah!

Anyway, I can record from EPG.

Hi scrowner,

I would not say "infancy", maybe young however very solid, and it works well. It is that there are lot of "undocumented features" in a good way so it is a lot like easter egg hunting Just think for a moment as to how many different hardware combinations it works on, and does it well!

You should be able to connect your rf feed also and those work normally. I just can't tell you exactly how. You could also use channel three to input "stuff" from the vcr as a manual record, family movies, etc. Lots of options.

I don't recall that being mentioned as a lot of setups are "different" from the norm, what ever the norm may be. Sorry if I left that impression as my system is probably about as abby normal is they can be, I don't print yet and the phone don't work, yet.

Anyway, best of luck and have a good day!
Mike
