[PD] 3gp videos with GEM on windows

[altern]

Hi

I am using 3gp video with GEM on windows and linux. Under windows XP on 
some machines pix_film does not return the right video length in frames, 
it returns 1, testing with same video and patches in another machine 
returns the right length. Does this sound like some Windows issue? maybe 
some codec that needs to be installed? I need to find a format for video 
that works fine crossplatform.

i also noticed since i upgraded to latest GEM that the 3pg videos play 
its sound after being loaded. This does not seem to be done via PD 
(sound is off), the sound plays once after the video is loaded. If the 
video being rendered the sounds keeps playing looped but chopped, with 
very short periodical interruptions.

thanks
