They play fine in totem; they seem to consume about 50% of each processor (if the System Monitor is to be trusted); I wouldn't expect that much but it's probably normal and at least they play smoothly. In pix_movie they eat 100% of one processor and run at about 4-5 fps or less.
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...)
