I began to see this behaviour with the introduction of ivtv 0.4. I began
to notice out of sync frames
This appears to be an issue with ivtv 0.4 from what I can tell. If
anyone can help pinpoint what version this behviour was introduced that
would help track down and fix the issue. Post your findings on the
ivtv-devel list.
It appears that the behaviour only appears when encoding at a moderatly
low resolution. Perhaps anything less than 720x480.
I see it consistently when encoding at 640x480 using DVD or MPEG-PS and
6000-9000 vbr.
There is a thread on ivtv-devel regarding this issue, the following link
also provides a video example and screen shot of what I was seeing.

OK - I don't know the best way to describe this, but recently (within
the past month) I am getting a 'random jump / skip / blip / pixelation
/blur / whatever you want to call it' on the bottom half of the screen
of my recordings. It lasts less than a second and is only a visual
annoyance (you don't really miss anything) and doesn't mess up the
sound. It occurs on all stations from what I can tell. I don't watch
a lot of live tv, but I haven't seen it so far through that.
I can't figure out what could be causing this. I hadn't made any
updates since this started occuring (at least that I can recall,
unless this had been occuring since the update and my memory is shoddy).
Any ideas? Thanks...
Matt
