Advertisements I'm sad to say goodbye to TiVo. I just bought a 50" plasma so of course had to upgrade to hi-def cable. Due to lack of a TiVo hi-def product, I was forced to go with Comcast's DVR, which is an inferior product. Lots of glitches... already had it replaced once. (But the hi-def is worth it). So TiVo... whre's your hi-def product? When I called up to cancel today, the rep said, "maybe by the end of the year". How can this be? Who's asleep at the switch? How could you not have one of these already!!!!!????? You must literally be losing thousands of customers a day - and we'll be hard to win back once we've got another brand installed. Someone in management's not doing their job.
