RiVA GUI has to be the best!
Frogger is more versatile and can play VideoCDs and view in little
windows, but for standard Amigas you can't beat RiVA GUI.
I think the rule is - the larger the resolution of the MPEG the slower
it will be. An '040 would be fine for 160×100 but for 320×200 full
screen it might be slower.
Riva Audio also has sound and the demo doesn't limit you to maybe 20
seconds of viewing time unlike Frogger. Although it does stop you from
using colour until you register.
As for AmiPeg, that is not very configurable but gives smoothe colour
results with no sound, and it's free.
