...ok, so I tried some old files that used to work with pdp_qt/ 
pdp_yqt, but they don't currently:  I can only guess that the fink  
version of libquicktime that I compiled the RC8 version of pdp/pidip  
has screwed up something...

...however, you could always use open the file in gem with  
[pix_film], then feed that into [pix_2pdp], process with pdp/pidip,  
and finally return it to gem with [pdp2gem]...you're especially lucky  
if you have the latest cvs of gem and pix_2pdp/pdp2gem, because I  
recently made the YUV/YV12 conversions fully altivec'ed (as are  
YUV2BGRA/BGRA2YUV)...

...another thing to note is that no matter what you use, you will get  
better performance if your movies have dimensions that are multiples  
of 16, like 320x240, 640x480, 336x224, etc...this will ensure the  
altivec path, and generally makes the cpu and memory managers much  
happier...
