I just switched over the policy to allow a local JDS Sun Ray login and tested.
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.

Regards,
Kevin

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) ?
