I keep hoping that some day I stumble upon some dev software for the PC-FX which can allow me to make Mjpeg movie discs for it. I will probably have to find some arcane Mjpeg capture card too and get it to work with win2k. I have seen enough games now on the FX to know it is possible to have pleasant audio and clear video on 80% of the visable screen, which I am guessing it about the maximum bandwith some part of the FX can deal with.
At least Anime Freak Vol 5 and 6 show you can put a very modern DVD like interface on to your Mjpeg videos with a menu, chapters, fast forward and reverse. The look of it reminded me of Power DVD.
