	Hey all... I've been trying to use my resolution test patterns to 
quantify the resolution softness I see with my PVR-250.  Thinking that perhaps 
it's due to the mpeg encoder part of the chip and not the analog/capture signal 
path, I've been trying to capture some raw frames.  I've recompiled the ivtv 
module with the FIXUP defined, but it crashes every time I try to grab anything 
(even with non-scaled 720x480 resolution).  Anyone ever try this?

	A way around it would be to capture the hauppauge-proprietary YUV 
format (default ivtv without the FIXUP) and post process it.  I've done some 
googling, but no leads on any code to do this.  So, basically, I can capture 
some data that vaguely resembles YUV data, but can't play it or process it with 

	Thoughts?... I'll try on the ivtv list too.
