I do have a Delfina Lite (software overclocked to 60 Mhz), 060/50, 604e/233, 128MB RAM, CVisionPPC,etc..
Using the latest version of Frogger and a scsi device to read divx from, I can watch most of the divxs` without frame skipping in 640/400-16bit resolution
(BTW Amp is sooo slow playing divx)
Delfina decodes the audio of the divx and it speeds up the movie a lot.
Problem is using vlayer modes or 24bit modes slows down playback a lot. And as you know vlayer hugely improves the quality.
I can watch mpegs without frameskipping using 512/384-24bit modes using vlayer and Delfina.
Still Frogger has audio/video unsynchronization problem on my machine. But I think it will be solved as the programmer of Frogger is a really great programmer.
