There is a thread on here somewhere about it, only a couple of months old.
The service is okay, the HD is too compressed for most people, the SD is better than most. Lots of HD Channels though. Whole home DVR is pretty nice, but some people think the DVR is lacking compared to Tivo. I don't have any issues with the DVR though, it does what I want, records new shows only if I choose, etc.
