The closest thing to the best we have it if you can hunt down a copy of
showmetv and watch and older mpeg through it. (I think mpeg 2).
You should get really decent video performance. That's the only video
app that takes advantage of a sun ray library that allows the xserver to
be bypassed and the video to be rendered directly to the Sun Ray.

The performance is drastically worse, but the sync is near perfect.
RDP = fairly smooth video + audio lagging 3-4 seconds
JDS = very choppy video (maybe as good as 2 frames/second) + tightly
synced audio.
I'm really surprised at how bad the frame-rate is being the only user
on an idle T1000. I must be missing some tweaks (stock /etc/system
file).
In case you're curious, I just went to youtube, searched for "daily
show", and clicked on "UCONN Daily Show" (just because it's a really
easy one to find with close-up of people talking so you can see the
sync, and it's what I tried on the windows side before).
I haven't tried building anything to play mpegs yet... not sure I'll
have time.

Kevin,
Do you see the same issue when you run the same video on a Sun Ray
server without using connector or rdesktop (ie. no windows involved) ?
