Sky HD Rip Off
I was an early adopter of Sky Digital and Sky+, and I pre-ordered Sky HD, however, when the demo boxes were released I took one look at the line up and picture quality, cancelled my order and haven't looked back.
For £10 extra a month, there's no content, and the quality's poor. In fact, the only channel worth having HD for is free - BBC HD. All the other HD channels show the same stuff on repeat. And soon you'll be able to get BBC HD for free on the BBC's Freesat Service.
And for movies? Just buy a cheapy HD-DVD add-on for an XBox or buy a PS3 and use BluRay and watch the movies in better quality (1080p) than the Sky HD service (720p/1080i) which still suffers IMHO from awful artefacts and pixellation due to limited bandwidth. Agreed, it's better than it was, but it's still bad.
