Thanks for the info. Well, I just started watching X-files (around 200 episodes), and the poor deinterlacing by the Lumagen is very noticeable, and distracting (I've tried all modes on the Lumagen by the way). I'm not looking foward to seeing that for the next year or two. Having the PCH output 480p is not very good either. Most of my SD DVDs are TV series.
I am thinking about maybe getting an Edge. But, I'm cheap, and so I might just put up with what I have now.
