Ok so not as good as I would have hopedI have tried 5 different players - Act1, Rockplayer, YXplayer, Real and MvideoRockplayer plays avi,mkv,mpg and mp4 but the audio is out of sync almost always not matter the framerate, audio rate or bitrateYXplayer - plays the best out there but locks up in about 2-3 minutes cant figure out whats going on there - but I cant get the latest version to load eitherReal - not really all that great has lots of issuesMvideo - has potential but has framerate issues with mp4 files and really cant seem to play anything else - the audio does stay in sync but the frame rate is hard to get overAct1 - almost exactly the same as mvideoFiles are anywhere from 800 x XXX to 400 by XXX - framerates from 15 - 29 and bitrates from 200 - 700 - nothing played idealAnyone have any luck getting videos to play without frame drops or audio sync?
