Well, it scaled properly, but the playback was jerky and unwatchable. 
Oh well - I guess I'll just have to live with it until I get a higher 
resolution display.  It seems to affect all the 1080i channels that I 
get, which sucks, but at least I should be able to transcode before 
watching stuff.  The only shows that won't work for is live sports, and 
I don't think the 15% loss off the right side of the screen will be that 
big of a deal in those situations.

Thanks for your help.
