Hi everyone. I've seen a thread which covers this topic - but I've started a new one, as the question is slightly different..... I've just downloaded the Act 1 video player (demo) from the Android Market to see if the sound and video are out of sync when using this media player - and they're not. The video plays perfectly. The downside is that to play more than 2 minutes, I have to buy the app - even though it's not a lot of money ($1.79), that's beside the point! I see that many people with this sync fault have reported it to HTC, but we're all waiting for a firmware update to resolve it. I think giving this app for free would resolve most people's issues!
