every second or so the audio stops for a little bit (<1/10 of a second
perhaps). the video also seems to pause for an equally short period.
the problem may only be with one or the other, and then the other one
just pausing to resync, i'm not sure. that's what i consider 'choppy'.

thats a little different. i notice minor jerks like that on cnn now
much less frequently, with the latest experimental + jitter reduction
code. it had been much more jerky before that, so much so that i turned
off the overlay, preferring the odd bit of tearing from the jerking i
was seeing. but now i have turned it back on and am pleased. my system
still jerks the cnn scroller more that i would like (maybe every 3-5
seconds), but its way, way better.
that's mytechnical definitions for 'jerky' and 'choppy' at least. :-)
i also intend on trying a new kernel or two. i notice someone else
mentioned that they had problems with both the low-latency and the
pre-emptive patches, so i might just try one or the other (probably the
low-latency?) and see if that helps or not. right now i'm running a
stock (custom compiled, but nothing out of the ordinary compiled in)
debian 2.4.20 kernel.
cheers,
