I'm running a patched up 2.6.9 kernel with alsa 1.0.7 right now, I believe. I
started out on a pretty stock 2.6.7 though.

On one of my 1080i stations, I got audio that sounded like it was underwater,
unless I changed channels away from it then back to it, which of course,
can't be done when watching a recording. I worked around this one by
switching to native ALSA output and passing raw AC3 to my amp. Both my 720p
stations behaved similarly to what you describe, a/v is fine for the first
second, then went to hell. There were slight differences between running OSS
eum and native ALSA (the audio chop was a bit different, but seemed to be the
same problem). I fixed this one by changing ALSA versions. Both 1.0.5a on a
2.6.7 kernel and 1.0.7 on a 2.6.9 kernel have behaved for me (or am I running
1.0.6 on the 2.6.9 kernel now?...).

*shrug* Beats me.

No problem again. ;-)
