So I have qtch files that apparently were created with QT 7+ because they can't be played (with QT 7+ or VLC) just by renaming their extension (as fileinfo.com says).
Any solution out there ?

According to Wikipedia the QT 7+ .qtch format differs only in the first 16 bytes compared to the QuickTime Player 6.x cache format. Therefore I'd suggest trying this command (but make a backup of your .qtch file first):
printf '\000\000\000\024\146\164\171\160\063\147\160\064\000\000\004\000' \
| dd bs=16 count=1 conv=notrunc of=filetomodify.qtch
It modifies the first 16 bytes of filetomodify.qtch
as described above. After that, you can rename it to .mov
and if you're lucky, playback will work.
