Tunebite issues

Has anyone experienced slowing down of tracks after they’ve been converted using Tunebite? When I try and replay them (either in mp3 format or wav), they are ever so slightly slowed down; for example a 3:50 song becomes a 4:19 song. I’ve tried changing all of the options around, but they just won’t convert at normal speed. This Sucks!

OK - If anybody else has this problem (however rare it may be), I replaced my standard soundcard with an upgrade, and that took care of the speed issue. Problem solved!
