Adding my 2 cents, in the hope that others more knowledgable may be able to reproduce the problem. Using a Nexus S 2.1 with the latest beta firmware, I find I lose audio sync when doing multiple "yellow button skips" to jump through commercial breaks, where there is a 30-50% chance the audio will be out after this. Doing a "green button skip" backwards almost always corrects it. Regards, Richard
