I've got a few racing downloads and find they play OK on a PC but sometimes my Laser media player or Panasonic dvd (media) player won't play it...or be it the Laser says problem with the video but only the audio can be heard. Also it can only FF at x4 opposed to a normal x32.
I'm not sure if their corrupted or fragmented because they play perfectly fine on a computer but obviously my 2 dvds 'usb media' players have problems with them could indicate the above.
I found some repairs for corrupt MP4s or a TS file.
I've tried Wondershare but the AVI doesn't play, Any Video Converter does it but either pixels the picture or the audio's crap so i have increase the rate so not to lose the quality.
I usually watch them on a TV rather than a laptop or tablet phone.
My main intention is if I can fix and retain them as the AVI source as just that then problem solved. I've found other specific file type repair tools but found it very hard to find on specifically for AVI.
