[PD] gem2pdp troubles...

[John Harrison]

xvinfo reports:
X-Video Extension version 2.2
screen #0
 no adaptors present

Perhaps I'm wrong that this isn't unusual. If I am wrong, how would I 
fix and does it matter or is pdp_glx just as good?

I'll look deeper at the objects you mention. I assume I can convert to 
quicktime by reading the video in with pdp_live~ or pdp_theorin~ and 
writing them back with pdp_rec~?

Any ideas about how I might fix gem2pdp? pdp2gem works great, btw...
