[Gllug] Mythtv/dvb card problems

[Paul Rayner]

Hi,

I've recently bought one of these:

along with a Hauppage mediamvp, which is working nicely playing mpegs 
from samba shares and nfs mounts. I am having some trouble getting the 
T200 to work. Googling (and dmesg) suggests that the card should appear 
as a v4l2 card under MythTv. When I go to set up capture cards, I am 
given the option of composite or s-video, but no "tuner". The channels 
option on the MythTv menu has the "scan" and "advanced" options 
disabled.

Is there an easy way to test this card? Most google results just say 
cat /dev/video0 | mplayer <args>, but my machine is headless, so that's 
not really an option, and there seems to be no way of setting a channel 
(there are a few tarballs which claim to be able to change the channel 
on dvb cards, but most of them are linked to from 2.4 howtos). I have 
tried cat /dev/video0 > test.mpg, but the file test.mpg is not 
recognised as a valid format by mplayer or vlc.

I have upgraded my kernel to 2.6.15-1 (FC4), but still no luck. I did 
have to change a jumper setting on the card, and wonder if that's 
somehow broken the linux drivers - is there any way to test this? I had 
to change from J8 to JX1 as the PC powercycled itself otherwise, and 
this is the course of action recommended by the pigeon English 
troubleshooting section of the manual.

I've been going round in circles of semi-useful online guides, and out 
of date sourceforge projects, so I'm hoping someone here can point me 
in the right direction! Below is the relevant output from dmesg, and 
lspci -v.
