[GEM-dev] pix_record issues with WinXp and Vista

[Loic Kessous]

I just see that I also have this problem and the 'quick start' doesn't  
work for me...also the 'codeclist' message crash pd on my computer.

Also, I don't know which codec to use, the codec message to send, I  
tried to use a filename with .mov to see if it can guess but it  
doesn't work.

does any body has a step by step method that works?
