Testing the same youtube video on N800 with beta 7 with mplayer v24 and sound/video are in perfect sync within Canola2 Beta7 whilst video is stretched. So for me there is a problem with Canola beta8 combined with mplayer 26, where if I play the same video in mplayer 26 only, sync on N810 appears to be fine. (Canola beta 8 = video/audio out of sync) So for myself with latest Canola2 beta8 on my N810 YouTube playback is currently worse with a lot more YouTube videos than appears to be case with Canola 2 Beta7 on my N800. Should I now try a Canola2 clean-up and fresh install of Canola2 Beta8 on N810, or would you first like additional test information etc.
