I have Adelphia "digital" cable. (The box has no digital outputs, so I don't even get 5.1 sound out of it.) It pretty much sucks.

The "lifetime" Tivo subscription is for the life of the unit...they only have a 1 year warantee. At $299 you'd be paying up front for 23 months of service. If the unit fails at 13 months, you're out one unit, AND $130. I think I'll be opting for the $12.95/month plan. I don't trust the units to last more than two years before failing.
