capture: DAZZLE 80 USB
System: AMD ATHLON, 800MHz
Sound card(dunno if this is neccasry to say) Nvidia rive tnt 16

When I use VIRTUALDUB and input an avi file so that i get a wav file, i get the sound but there is a hiss sound on the background. I dunno why? Thus sound sucks.
Can someone help me on this one?
Thanks,
