another piece of test code) :-P

What can i say? It works perfectly! I'm still wondering what are the
steps to convert two 216 frames into a 690 block, but that's probably
for tomorrow morning... ;-)
Thanks a lot for the hack, i'll try to convert it into something more
"user-friendly", but at least i know what to look for.
Cheers!

P.S. for vladimir: i tried only one of your captures, and it seems to
work fine. Tried with some local captures, works as well ;-)
