Hey, Sometimes when I convert to avi files, it either won't play cause of the size not being right or it's not the right codec. The codec should be called xvid. If you already are using a converter, make sure that the codec of the avi is set to xvid and that the size is correct. xvid is just the type of avi video file. Either way, there's a link at the bottom for your possible solution. I have a mac too. Mac's are superior in every way to pc's. The only issue is that only the best products are compatible so there's only so much variety. If you know of an mtv video converter for mac, let me know.
first you should know what formats does your mp4 player support. and i remind you that when you convern the format, please set up the size of video. if the video size is too large, maybe the error will still appear.
Transferred avi files sometimes playable sometimes not
When I transfer files form my PC to the MP4 (Rockchip 27) sometimes the file is playable and after I have transferred some more files the next files are not playable
I Format the MP4 and start again and different files work - very touchy - what's going on?
