Recover file that states "excellent"

Hi everyone, it's a wonderful programme however i am a little confused,

i managed to recover the lost files which recuva says:

State: excellent

Comment: no overwritten clusters detected,

so I downloaded them to the desktop

they are .avi .flv .mp4 and movie maker files

firstly there were no .flv files on the stick, they were vob files but for some reason the .vob files have become .flv which will not play on any player I have tried (3)

some .mp4 files play but not the ones I want and the movie maker files wont play either, any advice please?

thank you so much
