ive tried .mov files and it does not play. havent tried other files though since i just bought it last night at GHills.
other than that, its fairly good for my needs and the price is cheaper than my nike basketball shoes which i use only twice a week hehe
70% of my video files are divx and avi files and it played without any problems. i'm very satisfied with it except from some quirks:
1. does not do chapter forwards and ff is up to 16x only which will be annoying for a long movie
2. menu structure is not that user friendly as stated in my previous statement.
3. tried two usbs plug, if you remove the usb that is not in use, the player will freeze. you have to restart the unit
other than that, im loving it.
watching all the videos i compiled in my pc of my 2year old together with her last night is priceless. the HD playback capability is just a bonus for me
i watched heroes s3ep13 and enjoyed sylar
