While playing back MP4 or FLV files in Totem, the player will constantly use around 50% CPU, and will also appear to skip forward with the video playback (the audio will continue correctly) randomly or when another program is run in the background.
This doesn't appear to happen with Ogg Theora video, so I assume this is a problem with the MPEG and Flash decoders.

I noticed in the upstream bug that you are using an Atom dual-core 1.60GHz. I'm using an old Athlon XP 2700+ 2.17GHz (333MHz FSB) and when playing back MP4 and FLV files in Totem CPU usage is around 40% but I don't see any skipping. Are you able to borrow a faster Atom system and test?
