IIRC it didn't need much in the way of installations, though the version from AmiNet is probably the new C version which may require more external stuff.

I reckon the VBR thing isn't a CPU power thing, seeing as I can play 320kbps files on my 060. Maybe it's just not supported by that engine, be it mpega or what not. I'm sure I've been able to play VBR files myself, but maybe that was with AmigaAmp or something...
