Just got a basic box (Series 2 - 40 hr DVR) for Xmas with lifetime service subscription. I have looked at FAQs and did a few searches before posting. Here are my questions: Is it worth considering upgrading to a unit that can burn a DVD (why bother if I can use TiVo to Go to transfer to a PC and burn one?). Seems more versatile to invest in a DVD burner on a PC rather than in a Tivo unit. Once I open the box and subscribe, I can't decide later to get a better box because my lifetime service agreement is wedded to the 1st box, right? Are there conditions where the box can quit working and I lose the lifetime service - i.e. can't get unit repaired or replaced and continue the agreement? Any info on how long I can expect the "lifetime" agreement to last?
