Is anyone having problems playing these? I've converted a few of my avi's to MP4 and try playing them using mobo and the built in player and none will play. I've used a few different converters ie 'Free video converter', 'Video to android converter' and 'WinAVI MP4' but none seem to play on the ace once converted Anyone got any ideas of what I could use to convert and play these. Free players if possible. Cheers.
