For a very long time I was using some early ivtv drivers and
mythtv-0.11. This setup worked perfectly and never gave me a lick of
trouble, but recently I wanted some of the new features so I decided to
download ivtv-0.1.9, linux-2.4.25, and mythtv-0.14. I used the latest
pvr-250 firmware from the hauppauge site and the latest v4l2 patches.
Capturing seems fine as I can play back the mpeg2 video with mplayer,
but when I watch live tv or play back a recorded video I get the video
in 480x480 resolution even though I captured it in 640x480. This causes
the video to be perfectly square and stretched. If I set my capture
profile to use 640x480 resolution with the 16:9 aspect ratio then
playback is right but the recorded file looks very wrong in mplayer. I
want the capture to be right so I want to use 640x480 with the 4:3
aspect ratio. Does anyone have any ideas on how to make the mythtv
player play the files correctly?
Also, I noticed that the audio sync is also slightly off, if I use the
experimental A/V sync that seems to clear it up unless I use FF then it
takes a second of playback to resync the audio. These problems didn't
exist in mythtv-0.11 so I wonder if there is some new feature I can turn
Anyone else with a pvr card noticing these problems?
