 	The -150 uses a different and newer video capture chip than the 
-250/350 (cx88 vs. saa7115). I'm curious to see if there's any difference 
in capture resolution in the -250 vs. the -150.  If anyone with a -150 
would care to check it out, the resolution test pattern DVD image I made 
awhile back is still up:

 	Cook it up to a DVD, play it in a settop player, and then use the 
capture card to see how much resolution can be captured.  In particular, 
the frame you want to look at is the one on the DVD that looks like:
