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 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.

I tried, not sure my syntax was correct. I still can't play it so I'm giving you a sample file (see link in question) so that you can try. – user2534 Dec 3 '11 at 23:52
It didn't work for me either, I'm afraid. – artistoex Dec 4 '11 at 0:53
