Hello,

I have current situation a client (win2k3) 1Gigbit net that using to edit video with flowing format HD 100mbit(dvcpro) + 4 wave Chanel audio , the media is located on storage nas(exanet ,redhat based). The issue is that while the client reading the video and when he needs to slide/scroll back the video the video is playing but the sound is getting behind the video lip-sync. I did a trace of 60 sec in around 22 sec to 27 slide/scroll back occur few sec after it we saw the sound getting behind the video lip-sync , in our video definition usually after 40ms DELAY we start to see lost frame or lip-sync issues . i did some analyze on the trace i can see that the storage having some delay read request issues few seconds after scrolling back the video more than half a minute and even more further. whats bothers me in the trace that when analyzing tcp.analysis.ack_rtt as well i can see that there is some periods of trace more than 50ms delays from both client and server , can i get into conclusion that the client suffer from some network congestion or also the storage?. any idea and tips would be appreciated since its one of my first smb analyzing. Please advice Thanks
