Hello!
I have a PVR-350, using ivtv-0.4.3 (installed by knoppmyth R5B7, for what it
is worth).
My problem is that the audio appears to be a fixed amount ahead of the video
(200ms or so?).
I have eliminated Myth from the issue by doing "cat /dev/video0 > test.mpg;
mplayer test.mpg". Works fine, except one can see the delay between the
audio and video. The setup is currently receiving NTSC over the air. It does
not matter what channel I am tuned to. I have no problem with other video
sources (DVDs, avi's, etc.). I even tried playing the test.mpg on a
different box, but the delay is clearly within the file.
Is this a known problem? Is there a setup parameter I missed? Could it be
something wrong with this PVR-350?
Anyway, here are the details of the installation:
