OK, some wins, some losses.

Two main issues left:

1) getting DVICO remote to work with MythTV,
and
2) getting MythTV to play TV!!

Thought I'd continue to post in here as my hardware setup is similar, although I have the Lite FusionHDTV card and wireless.

I have the HDTV DVB-T Lite card detected and configured for MythTV now. I have my Dlink DWL-G520 working. :D I have patched lirc and get the remote recognised and it shows key presses with irw, but doesn't work in MythTV. Something else I need to do?

I cheated with channels: couldn' t seem to work them out, so I doctored Greg's script and loaded them into the database that way. When I ran myth-steup they are all in the channels bit. Nice that he's in the same town as me! :D

But the bit difficulty is that when I try to watch TV on my monitor with mythtv, it doesn't do anything. If I run mythtv from xterm, it gives a black screen then exits with this:

Code:
root@mythtv:/home/mythtv#

What am I doing wrong, and what do I need to change?

Almost there now.....

Thanks
Mick

You may be out of luck if you used my channel info. I am in the foothills and receive UHF transmissions from one of the tall buildings in the city. You will probably want to receive the standard digital transmissions from Mt Lofty. Look on the dba.org website for the channel frequencies (They wont be the same as mine). I think you really should scan for channels in mythtv-setup. Make sure you create a transport for each channel. Specify the frequencies (from dba.org) and specify a bandwidth of 7MHz leave all other parameters for each transport set to Auto. The do a full scan of existing transports. If this doesnt get you the channels then there is something else wrong.

The other thing to remember (which has been done to death on the forum lately) is to ensure that you have a valid start channel in the input connections part of mythtv-setup.

OK, another new problem. Well, actually, an old problem revisted. Tried to set up scanning for channels in mythtv-setuip, and it said it couldn't open card! So went back into capture cards setup, and it said "Could not open card #0! Device or resource busy"

Arrrghh!! :cry:

Tried rebooting and same thing. dmesg shows the card as Nigel had described (Zarlink). What now, before I lose even more hair. :roll:

Thanks
Mick

After you have been through mythtv-setup the first time (during the knoppmyth install) the backend is started and will open the card. If you subsequently run mythtv-setup in order to do anything that needs the card (such as scanning channels), you must stop the backend first.
Code:
/etc/init.d/mythbackend stop
(i think thats the command)

Yes, I had just found that with a search. It's actually /etc/init.d/mythtv-backend stop. :oops:

I had assumed that by "exiting" mythtv it stopped it. Wrong!

Now I have a card again. Just need to scan for channels. I started, and set a MHz frequency and then 7MHz bandwidth, and it found but didn't progress, and said it couldn't open it. Keep trying....

Thanks for the help.

Cheers
Mick

OK, channels scanned and working (except for SBS - what is different about UHF??).

Still no remote in MythTV. Any ideas what to look for?

Thanks, almost there... so close.... :D

Cheers
Mick

Did you do all the steps in my script for the remote? It would have involved finding an old version of lirc (that is compatible with the patch from chris pascoes site)

Yep, did that. Will be following it again in a minute as I am reinstalling (stuffed up XF86config and didn't back it up first... :oops: ). As I said, I could do a irw and it showed the remote key presses, but6 it just didn't work in MythTV. Will follow same steps and see what happens this time. Currently recompiling with latest madwifi to allow me to use my dlink wifi card.

Cheers
Mick

BTW, while my kernel is compiling I looked at Chris Pascoe's site, and he used this instead of irxevent, so I may try that if your steps don't work for me.

Thanks
Mick

Update: reinstalled, and now have everything working! :D

- Had to add dvb-bt8xx to /etc/modules to get DVICO card detected.
- Had to recompile4 kernel and recompile latest madwifi to get Dlink DWL-G520 working.
- Had to find old lirc version and patch with Chris Pascoe's patch to get remote working. Greg's script instructions didn't quite work for me (couldn't find the lircrc he mentioned) so I used these ones.

Am pleased to report that EVERYTHING works now!! :D.

Thanks for the help.

Cheers
Mick
