[PD] Gem in WinXP displaying 8 bit color resolution

Gem in WinXP seems to be working ok but shows all video in what looks to 
me like 8 bit color resolution. This is the case whether using 
|pix_video| with a webcam or using |pix_film| with an avi. Other movie 
players and capturing applications appear to be showing in video 24 or 
32 bit  color resolution. Anybody know why this might be case or what I 
might try? Changing the colorspace of |pix video| doesn't help, and even 
the Grey colorspace looks pretty bad --- like there's only 4 bits of 
Grey resolution or something...

Probably unrelated: I'm getting an "invalid enumerant" error in the 
console for each rendering cycle. I am texturing onto a rectangle --- 
when I texture to something other than a rectangle the problem goes away 
(although the 8 bit color resolution problem remains.) However if I send 
|mode 0( to |pix_texture|, the problem does not go away.  Both these 
ideas were suggested in earlier threads on this list about this problem.

Thanks in advance for the help,
