As if Tivo doesnt have enough problems

ZDnet claims that Google might be working on their own DVR

It is very possible that Google is creating their own branded digital television DVR / satellite service.

A DVR that lets you "Log In" with your Google Account before you begin your television watching would allow Google to serve up relevant ads based on: the program you are watching, your search history, the type of emails you have received in the past 24 hours (excluding spam hopefully), or anything else Google can track.

Imagine the possibilities… You are watching Google Satellite TV through your "internet ready" Google DVR:

1) You receive a new Gmail and it pops up automatically on your TV (if you choose to see new messages of course).
2) A ticker at the top of the screen shows recent news that interests you… or better yet, it shows new items from my Google Reader!
3) A more personalized TV experience which will serve up relevant commercials on commercial breaks based on your interest

Of course this might be another one of those Google can do this thing rather than anything based on real information.
