I've noticed a difference between programmes on the same channel too. Usually HD programmes and films are quieter, but that's due to the way HD is broadcast using Dolby Digital, and the fact films have more headroom for effects. Ads are sometimes louder than programmes, but that's probably due to compression effects to make them seem louder, so you take notice.

BBC HD is also guilty of making their idents (the bits with the cat that turns into a lion, etc) very loud.
