I hope this is right section to put this query under. I am using WindowsMedia Player 10.00.00.4019 under Windows XP Home Edition Version 2002 Service Pack 2

I filmed some movie clips on my camera and saved them to my memory stick, and later deleted them, thinking that I would not need them again. I then realised that I did and so recovered the 13 clips from the memory stick using PC Inspector File Recovery. I now have all 13 clips back but only three will play.

When trying to play the other 10 I get an error message saying:
'Windows Media Player cannot play the file. The player might not suport the file type or might not support the codec that was used to compress the file.'

Why can some play and others not? I have not done anything different to the three that can play.

I would be greatful for any help!
