Just thought I would share; there is a new(er) Divx (or Xvid, Ogm, etc.) player called BetaPlayer. If you ever tried playing divx files with pocketdivx, it was probably slow. Picard (the author) re-wrote the program from the ground up to be much faster and efficient. Correctly encoded divx file's play perfectly at 15fps on my casio E-115.
BTW: I was looking for an HPC with a large screen, and I'm torn between an Epods, a TriPad (vadem clio) or a PenCentra 130. They all have about the same processor but the tripad has a keyboard. BUT the other two have either 2pcmcia slots or a PCMCIA and CF slot. >_< What I really want to do with these is edit photo's on the road without the lag (and weight) of a laptop.
