Can't really answer. I have only a 1080i-capable display, and the  
only BR disk I have is the "Taledega Nights" that came with the PS3.

I use the "Elephant Dream" HD file to test and it looks as good as  
the BR disk on my 32" LCD, in fact the ED file actually looks better,  
but remember that it was computer generated, not shot on film and  
then transferred to video. I have no way to tell if going to 1080p  
would actually improve things noticeably.

Bob is a de-interlacer AFAIK, not a scaler. I don't have problems  
with interlace artifacts with any of my HD sources, but I haven't  
tried to get off-the-cable HD recordings yet.
