For everyone having lip Syncing, lip Flapping issues (audio and video out of sync:
This has worked for me:
In TCPMP:
Options > Settings > Select Page > Advanced
Change "Manual A/V offset +/- to -400

That seems to be perfect.

Now my problem is that youtube doesn't work with this.
I have the newest Rom update from HTC,
When I click a youtube video from youttube.com it freezes for a few seconds, up to about 20 seconds, and then i have control of PIE again.
Google Videos works perfectly though, and i have access too all youtube vids from there just fine.

I want to add that on wi-fi it works most of the time, on EV-DO it has the freezing issue.
