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 On 12/6/06, Sangeeta Varma <[EMAIL PROTECTED]> wrote:
