Completely anecdotal, but I occasionally download videos from YouTube for 
later viewing, and I get .mp4 (MPEG-4: H.264) files - which is probably 
what's in the .mov container as well.  (.mov is another one of those 
container formats that can have a lot of things, but these days I believe 
the 'default' is H.264.)

YouTube is probably saving them into some temp storage and then converting 
them at their leisure, would be my guess.
