Lost season 5 is now available in HD on the UK iTunes Store. As far as I know it is the only show available in the UK in HD. HD Episodes cost £2.49 as opposed to £1.89 each, the season pass is £41.99 in HD as opposed to £31.99 for SD. The only HD video available before today in the UK store was film rental via Apple TV (and podcasts too I guess).
The are in 720p / 24fps. On the free starter kit my iTunes shows a strange SD-HD logo, whereas for the episodes there are separate normal (ie. no logo by them) video files and HD files with HD next to them.

[Edit: sorry I just realised I've probably put this in the wrong forum and someone else has mentioned this in the iTunes forum - I didn't see it before, sorry!]
