Yeah - what a dumb ass way of programming.

I also got caught out and missed the first half of Casino Royale... My fiancee wanted to record Romy & Michelle's reunion, and I saw Casino Royale on straight after, so I thought, great! I'll set a 5 hour timer and get them both.
But after watching the first movie and gearing up for Casino Royale in HD, the bloody thing starts half way through (with a helpful ch 7 announcement saying they are going back to normal programming).
Thanks a lot!
