Yeah, that 880x480 mode fits pretty much perfectly. But I have a 47" Panasonic 
and different cabling than you, so I certainly wouldn't expect it to work 
perfectly for your TV. A while back, I found a great web site where you can 
import a modeline and then click some buttons to adjust it and have a 
resulting modeline spit out, but I can't recall where it is right now (and a 
quick google is failing me). I've got it bookmarked at home though...

Oh yeah, if that mode is pretty close, you might just try firing up xvidtune 
and see if you can use that to coax out a better modeline.
