Replying to my own post - It looks from the code and what docs I can 
find as if the MPEG stream will fill the 4:3 picture, and can be 
stretched/unstretched by the TV as desired, but will not be otherwise 
scaled by the PVR-350 (I assume it does not output the VBI aspect ratio 

Oh well. Looks like it is possible to modify the output window size and 
scaling of the image in the PVR-350 decoder. Has anyone played with that 
yet? Shall I just buy one and have a play myself?
