Hello,
I've built a MythTV v0.14 system with an old dusty bt878a capture card I
had lying around and had it working great. I decided to buy an ASUS TV
FM card with the saa7133 chip and replace the older bt878. I patched
and rebuilt the kernel and modules and the card is detected fine on
bootup. It works great under xawtv 3.91, with a great looking picture
and excellent sound. However when I try to watch TV in MythTV all I get
is a black screen and this printed on the console:

This is the strange part as I have not touched the audio system at all
and I can get audio from xawtv. I have tried both alsa and oss. I can
drop my bt878a card back in and it all works great. Reinsert the
saa7133 card and it errors out. I've rerun myth setup, although
everything is the same, /dev/video0, etc. I'm out of ideas, please help!
Eric
