Dude, calm down. I have read several of your posts regarding MH
lately and you seemed to be particularly concerned with your in-flight entertainment. Here's a website where you can check MH
or specifically to IFE:
They have information about Select Plus as well as their new System 3000i (which unfortunately you won't be enjoying since the first re-configured B744 is not expected to rollout until Feb. 2005).
I can't tell you which planes have AVOD installed, but I would expect your flight to be one of those that has AVOD since London is one of their prime destinations. Just chill down and I am sure you will have an enjoyable flight.
