I had to change the mplayer line from pal to ntsc, and that's all I changed, so I ran:
mplayer -demuxer rawvideo -rawvideo ntsc:format=hm12 /dev/video32 Earlier in the day, video appeared just fine in the mplayer window, but I checked it later on in the day and I got this weird image where 2/3s of the screen was used by the channel I wanted (I used ivtv-tune) and another channel took up a different 1/3. The exact same command that produced this produced a perfect image hours earlier. Here is a picture of what I'm talking about: http://chris.luethy.net/get_photo.php?id=670 Also, while this corrupt mplayer was running, I ran the v4l2-ctl --log-status command. Here is it's output: Status Log: ivtv0: ================= START STATUS CARD #0 ================= ivtv0: Version: 1.1.0 Card: WinTV PVR 500 (unit #1) <4>ivtv0: All encoder YUV stream buffers are full.
