Yeah, it's looking like the Onkyo 809 is the only one that meets all the criteria. Maybe I'll grab one with a warranty.
Ross, to my knowledge, the scalers in middle-high end receivers are worlds ahead of the ones in our tvs. The industry is only concerned with displaying hd content the best, so the only put basic 480i/480p scalers in the tvs. This also keeps cost down. Companies like Onkyo and Denon put some of the best scaling chips on the market into their receivers. Even my Onkyo Tx-sr605, which only does 720p scaling, shows a huge difference on my Samsung Ln52b750.
