It's not your system. I have tried streamer on a dual PIII 800 with 512MB and a 10,000rpm Ultra160 drive and still lost audio / video sync. If I get any free time in the next couple months I am going to try and see if I can hack some better A/V sync into streamer. --Tom ----- Original Message ----- From: "Andrew A.
