aha - but thats the nova-t MCE (media centre) edition, which is different
Microsoft Windows Media Centre edition ought to include a remote - so that why they can get by without it. Since you are using linux i dont know that i would recommend the MCE remote - it depends if its supported by the kernet and lircd - perhaps somone else could advise if they have used this card and what they used remote wise.

well,
The IR port is still there so I guess I could acquire a Hauppage remote from somewhere and set that up. I quite like the Hauppage remote.
In the long run however, any sensor that I use (whether USB/Tv Card IR port/serial) is still going to look ugly. This kind of ruins the whole 'set-top box' feel.
I'm sure they will eventually have IR sensors built into these mini-itx cases as standard. Until then I'd be happy to put a drill through the front of my case and hook up an internal infra-red sensor.... if only I knew how that could be done!
P.S. No Windows remote control comes anywhere near my mythbox! I feel bad enough having to use ndiswrapper to interpret WinXP drivers for my wireless card.

Compiling a 2.6.13 kernel seemed to work for me.
The remote works fine and dvbscan finds the channels. I even succeded in getting tv_grab_dvb to dump a nice xml-file with the EPG. Tzap says FE LOCKED. (I haven't downloaded and compiled dvbstream, if I have to download and compile yet another piece of software I'll get rid of KnoppMyth and instead go for a plain Debian/testing....)
BUT, now I'm a bit stuck... Because I can't scan from inside mythtv-setup. I get tuning errors, even though I specify a starting frequency as I got from dvbscan. I even tried creating transports with those frequencies (but everyting else set to Auto) but no success.
If I only knew how to fill things in I might be able to set the channels up manually (it's only 5 channels), but I'd rather not mess with MySQL directly...
Also I'm wondering how to get things working correct with tv_grab_dvb. Since to be able to scan I have to set up a video source. And to set up the source I have to select a grabber. And tv_grab_dvb is not listed (i downloaded it myself).
Are the available grabbers compiled in myth or is there some config file I could change? (Would it work?) If I don't get things wrong, mythfilldatabase runs the grabber, where is the setting from which it knows whick grabber to run?
Is my best choice to recompile mythtv with DVB EPG support? (I read that it is an option.)

As for the settings....
UK Specific Settings
Bandwidth: 8MHz
Inversion: AUTO
Trans: 2K
Hierachy: none
Frequency: e.g. 75126660
That utility you've just used...
Has that created the xmltv file that is supposed to go in
/home/mythtv/.mythtv/RadioTimesUK
and looks like...
channel itv2.itv.co.uk
...etc
????
P.S. Have started compiling all of this to a 'walkthrough' - draft 1

By looking at the file created by dvbscan I could get scan to work by setting a frequency AND the other options. Leaing them on Auto did NOT work. (Note that I'm not a UK resident, I live in Sweden.) I didn't try which options were important, I just sett them all (8 MHz, QAM 64, 2/3, 1/2, 8K, 1/8).
I think I'm very close now... The problem now is that the machine is going to sit in a room without a network cnnectionm, thus I have to use tv_grab_dvb, but in mythtv-setup I can only chose from tv_grab_se_sweb and if I then try to feed the output from tv_greb_dvb into mythfilldatabase I get errors (it was late last night when I got that far so I don't remeber the exact error).
I'm not really getting the relation between all these Channel No, Channel Id, XMLTV ID etc. For example, why can't I watch live TV without an XMLTV ID? Isn't that only needed for the TV Guide? Is it also used for tuning in some way?

You should not need xmltv_ids for watching tv - they are only used as identifers for channel listing collection. Did you make sure the start channel is set?
Did you also try running the backend from an xterm and watch the error messages (or tail the logfile from the backend log).

Ok,
With a name like Nermander I shoud've guessed you weren't British...
I agree that the relation between Channel ID, Channel Number, Callsign, XMLTV ID etc can be confusing.
So, what happens when you go to Watch TV?
What error messages are you getting?
What hardware setup have you got?
I don't quite understand your predicament with the wireless situation.
1. How does using tv_grab_dvb avoid the problem with having no wireless connection? Does that grab the channel info from the airwaves in the same way as a set-top box? If so, thats clearly the way forward.
2. Can you not buy a wireless card for your mythbox or do you not have a wireless router setup in the house?
Also, where did you get these from, are they outputs from a DVB-tools utility?
Bandwith: 8 MHz
Trans Mode: 8K
Constellation: QAM 64
LP Coderate: 2/3 ??
HP Coderate: 1/2 ??
From my dvb-tools output (freeviewchannels.conf).. I get two types of transports:
A) QAM 64 : FEC_2_3 : FEC_1_2
B) QAM 16 : FEC_3_4 : FEC_3_4
(is the first FEC the LP? and the second FEC the HP ?)
Incidentally the channels that run on transport type A) are very choppy so I might try changing these from AUTO to see if that improves anything.

The problem was I was getting several different errors when trying to get things to work. Among other I got something like "No XMLTV ID set2. That's why I was so confused. No I have almost gotten things to work... One problem was that the start channel seemed to change. In Sweden we have channels SVT1, SVT2, TV4 etc so we want to use one digital channel numbers (as long as we use FTA channels). So fro SVT1 I used channel No 1. Set start channel to 1 (default was 3 for some strange reason). BUT, when I have tried watching live TV and go back it is set to 1280! I change it, exist mythtv-setup, go back and verify (it's still 1). Start backend and frontend, go to watch live TV, and it's set back to 1280... So I changed the channel number of SVT1 to 1010 (which I think is it's PID) and changed start channel to 1010. And it works! Where is this start channel stored? Why can't I set it to 1 when 1010 works lika a charm? Now I'll have a look at how to get the remote usable... It seems as if there's no key associated with Esc (so when I'm in the EPG I can't exit...) Quote: 1. How does using tv_grab_dvb avoid the problem with having no wireless connection?

Yes, that's what tv_grab_dvb does. I found out that the support for it is included in MythTV now, but I'll have to recompile with it turned on to get the checkbox in the settings. And I choosed KnoppMyth to avoid a lot of compilation... Quote: 2. Can you not buy a wireless card for your mythbox or do you not have a wireless router setup in the house?
I have no wireless router setup yet, I'm a poor man. The Pundit is the fastes computer I own, most of my machines are like P133:s with 1 GB disk and maybe 128 MB RAM. Quote: 3. Are these the standard settings for Sweden? Where did you get these from, one of the outputs from a DVB-tools utility?
Bandwith: 8 MHz Trans Mode: 8K Constellation: QAM 64 LP Coderate: 2/3 HP Coderate: 1/2
No, not for all channels, but for the FTA they seemed to be the ones. And yes, I got them from dvbscan. But they can also be found on Teracoms homepage (Teracom is the distribution organisation, they handle the transmitters only, no programs). I think 8 MHz and QAM 64 is common for all channels, but coderates differ a bit.

Yeh I have the same problem. There are about 4 channels (BBC ones I think) that use 1010,1011 etc as the callsign. These appear in Channel Editor after running mythfilldatabase.
These channels have the correct tv guide data but they do not tune in (reverts back to last good channel if selected). Meanwhile the BBC channels with the correct callsign do tune in but do not have the correct tv guide data. Its all very confusing because they share the same channel numbers aswell.

But isn't the link between the program guide and channels the XMLTV ID on the bottom of the Channel Editor channel setup page?

Yeh the XMLTV ID links up the channel to the program guide.... I think I probably have a mis-match caused by a typo in the Channel Editor, or maybe channels specified in one place but not another.
Did you ever get much luck with that DVB_scan?
Would you recommend it or is it more trouble than its worth?
How long does it take to grab the channel info?
P.S. Anyone who lost wireless after a kernel upgrade will need to re-install ndiswrapper. Its a quick and painless process.

ok, nermander I had a go at "dvb_scan"..
http://www.darkskiez.co.uk/index.php?page=tv_grab_dvb
I untarred it and replaced the sample channels.conf file with the one that I made with dvb-tools.
I then did
./tv_grab_dvb [-t timeout] > whatson.xml
Which creates a whatson.xml file looking like...
Code: <channel id="25664.dvb.guide"> <display-name>The HITS</display-name> </channel> <channel id="27072.dvb.guide"> <display-name>Men & Motors</display-name> </channel>
<programme channel="8384.dvb.guide" start="20051009123500" stop="20051009134000"> <title lang="eng">T4: Pepsi Max Downloaded</title> <desc lang="eng">Westlife: Pepsi Max Downloaded gives fans the chance to see music artists up close and personal, as they stage an e$ <video> <aspect>16:9</aspect> </video> <audio> <stereo>stereo</stereo> </audio> </programme>
If I do
tv_grab_dvb|mythfilldatabase --no-delete --file 1 0 -
It reports that it has made no changes.
Where do I go from here?
I can't seem to find any documentation on this program.
