Well after a weekend getting dual tv cards working, I am back to my original
setup... sort of and no video from mythtv.
Basically the steps I took as I remember it are:
1) recompiled the kernel to resolve some issues I was having with he ide
driver from my last compilation hanging on bootup. Added the btaudio driver
as a module etc.
2) added the 2nd tv card, the original was an ATI TV Wonder, while the
secondary card was an Aims Labs Video Highway Extreme, after much mucking
about with modules etc, I got both cards working with xawtv. For those who
want to try this, here is the relevant section of my /etc/modules.conf
alias char-major-81 bttv
options bttv card=63,14 bttv_verbose=2 tuner=2,2 pll=1,1
post-install bttv modprobe -k tuner
post-install bttv modprobe -k btaudio
post-remove bttv modprobe -r tuner
post-remove bttv modprobe -r btaudio
The last 4 lines are probably not necessary, but ymmv.
3) I installed the commercial OSS drivers and then uninstalled them as I
couldn't control the volume wrt mythtv or xawtv from ossxmix.
Anyhow, after I got this up and running, I tried running mythtv and all I got
was the usual info in the term window, I could hear the audio in the
background, but, not video window. Same result if I went through
mythfrontend. Oddly enough before I had got both cards running I had set a
recording to record a show. I had everything running around the same time as
the show would have been recorded. When I started up myth from either the
frontend or mythtv, it would say that myth was already recording the show and
would I like to watch recording in progress, I select yes and it comes up,
but it's quite jerky. Hitting V to switch to the other tuner fails.
Basically then I have to escape to get out of myth. I hit esc to get back to
the frontend, then have to go to the terminal window and hit ctrl-c to kill
the frontend, as it just sits there with the logo in the background but no
One the recording time period was up, if I started up myth, I'd get sound but
Since then I've removed the second card and rerun the ./configure, make, make
install steps, copied back my settings.txt that I'd previously backed up and
all I get is sound but no video.
Any suggestions on what I should be looking it?
Oh just remembered one other item but I suspect it's may not be related.
Since I recompiled the kernel, I had to reinstall the nvidia binary drivers.
Other than that, I can't think of any thing else.
