Today I found myself with a spare 20 minutes, so I decided to look into some HD TV stuff. I have a Telewest TV Drive on order, and already have an HD-ready TV, so I can look forward to some tasty HD content in the future.
Now, my TV Drive was ordered mainly for the PVR functionality, so I can record programs on my Telewest cable service in the same way that Sky+ users can record their programs. The HD capability is more of a bonus for now as content is very limited at the moment, but I happened to know that the BBC will be broadcasting World Cup matches in HD, so I rang Telewest to ask what I'd have to do to watch them. The answer? - nothing! There will be a new channel appearing on Telewest shortly which will be BBC HD, and since all the England World Cup matches are on free-to-air BBC channels, I don't even need a premium sports channel subscription. Nice :)
Whilst looking around at what other content might be available, I stumbled across the Sky HD site, which (no matter what you think of the company) is a stunning site, but you'll need a decent computer and broadband to appreciate it.
If you're not sure what all this HD fuss is about, then you might want to try the Wikipedia entry or the more UK-centric Burn Your Bonus HD TV FAQ.
