Hi

I have one of those damn WinTV GO cards with the 881 chip, and I'm trying 
to get it to work with MythTV. I've commented out the "usingv4l2 = false;" 
line (yes, the right one :P) in NuppelVideoRecorder.cpp as I read in 
another post here, that got rid of the "VIDOCGMBUF:: Invalid argument" 
error. But now I'm having another problem, and I can't seem to find any 
info about it here. When I select Watch TV the screen goes black and the 
backend dies with the following messages:

root at mediabox:~# mythbackend

I'm running MythTV 0.13, kernel 2.4.23 patched with v4l2 support, and 
0.0.1 of the cx88 drivers from bytesex.org. Also I have some problems with 
xawtv. Most of the screen is green, and only 1cm of the top is real 
picture, sound works fine. But the strange thing is, when I start 
recording with xawtv, the picture becomes just fine with sound and all.

Any suggestions?
