During playback, the picture pixelates (is that a word?) rather badly during any scene with lots of motion. Playback is using Xv, and audio is esd. The comments from teachers is that 'Microsoft plays it back perfectly so why doesn't Linux'. I am just guessing that the difference is a local install (Windows) vs how the thin client works. So, any suggestions on how to improve the playback? I tried using -framedrop, which helped sync the video/sound better, but did nothing to actually improve the picture. I have also noticed that MPlayer detects a server lag (about 0.56s), but shows no network lag/compensation. Has anyone else noticed this on with their installations? If needed, I can look at upgrading the switches if that is the issue. The servers are dual 2.4GHz HT Xeon with 6Gb memory, but the problem occurs with even 1 user. Sincerely, Dave Hopkins
