I have a 50" Toshiba projection TV. The owners manual says, "The colorstream HD jacks can be used with Progressive (480p, 720p) and Interlace (480i,1080i) scan systems" I don't know what any of that means. But...

I am considering buying a Tivo receiver with Hi Def. My question is: With this TV will I get the complete Hi Def picture? Or do I need to get a Plasma? Basically will I see the sweat coming off Brett Favres face?
