I have not messed with the channels or AHI settings, I have AHI6 .. will try it right away
edit: get the k-lite codec pack, and the mplayer inside can play 3gp... also quicktime and realplayer will play it... it is low-res though...
edit2: I have AHI 6.2 and use the 512i, a fortemedia card... there is no channel settings, and there is still audio distortion when scrolling... perhaps it is a g-rex related issue, the paula version works perfect. lowering the samplerate of the 512i does not help either...
