I tried out FroggerNGwarpos and works great.
Only not with sound.
With sound processor has to much load.
But mpeg and AVI are running great on my 604e 233Mhz without the sound.
Gues you have to have a Hardware decoder to get rid of this.
Btw frogger is the only player for me that will play the AVI files.
I only have got to register this version of mine.
So Frogger is my choice.
