Now the problems with iPlayer have been addressed, I've had TiVo installed today. A bit risky just before xmas, but what the h*ll (!)
It's about what I expected from the comments others have made. Better than V+ is some areas, lacking in others. The HD quality is excellent, same as V+, SD is acceptable but not quite as good as V+. Didn't really notice the difference between HD and SD on my 32" LCD on the V+, both were excellent pictures. I can definitely notice a difference with TiVo. It's still very acceptable quality, I suspect it would be more of an issue on a larger screen.
iPlayer I've tested a couple of times and hasn't crashed, but the picture quality is nowhere near as good as the catch up service on V+/VHD, and it's more awkward to access. Definite backward step for no good reason.
On the plus side there's the recording space and extra tuner and hopefully things will continue to improve. I've networked and had fun with TiVo Commander, with the rest of the family just wondering why the channel is changing
Looking forward to the VHD getting TiVo software and I can network that.
Overall a very cautious thumbs up so far. If it didn't mean mean my package working out a bit cheaper suspect I wouldn't have changed. Just hope I don't wake up to the lights of death tomorrow...
