Videos are so laggy that they can't play

The video plays for a fraction of a second and then freezes, with a tiny bit of audio looping over. I've tried playing different file types, playing from different drives, installing various versions of Movian/Showtime, changing settings such as buffer. Even videos that the XMB can play are unplayable.

The only thing that works for me is the old Showtime 3.4 (and probably earlier) available here:

Any idea what my problem might be? This is very disappointing because the latest UI and features are very nice!

Edit: Just showing that I'm still here. Also, I'm running 3.55 Rogero CFW.
