I have been using the PVR for over 2 months now and I can't imagine watching TV without it! Everything you read about it is true. It can do anything you imagine with it. Record while watching two channels, record while watching a recorded programme. If you want to do it, you can.
Hopefully in the future one will be able to plug a DVD writer into the unit so that one is able to back up recorded programmes, especially series.
One great thing is that you never have nothing to watch on TV. Even on Friday and Saturday evenings when the channels try damn hard to get you out of your home, you are able to catch up with everything that you have recorded.
I am still to use more that 30% of the 80 hours of hard drive space on the PVR and it's so easy to use, even my 5 year old son knows how to record, play back and pause live TV.
Sports fans will love the PVR as you can hit record on your favourite channel and watch another or go out or whatever you want.
Drawback? No backup, yet. Also, the hard drive is on all the time unless you set it to go to sleep. If you watch TV during the time the drive is asleep, it takes a couple of minutes to switch on. I don't like waiting. Another problem is that if two programmes overlap by a couple of minutes, you can't set it to start the 2nd programme a little later, so you tend to not be able to record it at all.
I would also like a search funtion in the programme menu and I would like to be able to set the PVR to record all of a programme. For example, when ER is on, record it! You have to do it all manually which is not great as I miss programmes.
If you have the cash, buy one!
