If a movie decoding induces frame skipping, the frame skipping consumes a
lot more CPU than the normal decoding. I've seen this happen in MAX as
well.
Can you put it in slow motion (play at a lesser fps than what's indicated
by the file) and confirm that below a certain wanted fps, it starts to
take radically less real time per logical time ? that should be when it
stops skipping frames.
The frame skipping problem does not happen for a file that doesn't have
b-frames (most notably, all files in photo-jpeg format...)
