The facts seem very shaded here. The XL has the 1TB hard drive and a glow-remote...I get that. And after that, the XL is THX certified...I get that too. But does that mean better hardware (processor, RAM, video card)? Or is the actual hardware the same (besides the hard drive space)? I'm looking to buy a 2nd Tivo for our house (1st is a Tivo HD) ...but if it's really just glow-remote and bigger hard drive...I'll buy the base Premiere for $72 bucks on Amazon, vs $248 for the XL. Hoping this group has some insight here!
