I’ve had one for about a year now and I’m quite pleased with it, I’ve never used the on demand bit though as my broadband isn’t quite fast enough for it. I think you need a minimum of 2.5k and I only get 1.8 – 2 (I used to get nearer 3k until BT ‘upgraded’ some of the wiring in the village but thats another story)
Picture quality through scart is pretty poor, HDMI is much better, the internal scaler is really rather good.
The one thing that really annoys though is that BT will update the firmware automatically and you can’t opt out. The last one added a 5min buffer to the end of recordings which is a great idea but the stupid thing wont ignore it if you’re recording two programmes one after the other on one channel and something on another channel, instead of doing what all other PVR’s do and record the two consecutive programmes without the buffer on the first one the Vision box gives a recording conflict and you have to delve into the record settings to set it to finish on time.
Apparently it’s easy to change the 160gb disk for a larger one and I’m going to do this soon.
If you’ve not got $ky or Virgin cable and you’ve got BT Broadband I’d get one, but don’t pay extra for any of the veiwing packs their not worth it IMO
