Varying R4 performance

Hey guys i had a bit of a hunt b4 i posted, couldnt find anything relevant. Apologies if this is a repost. Firstly R4 is an unbeleiveable program, keep up the good work!!!
My specs firstly
AMD Athlon 2600+
+1Gig Ram
NVDIA Geforce 4 mX 128mb
shit loads of HD space
My problem basically is that R4 can run with about 3 other programs (in standalone or with the winap plugin) and get 60-70fps no worries
But it seems as if a select few visualizations seem to send it nuts. It slows to about 10-15 fps, and the sound from winamp (regardless of plugin or not) plays at a reduced speed with a crackling type of interference. It might happen every 20 scenes. Just a bit phased by it all, if anyone could make some suggestions it would be very much appreciated
Cheers
