Well I sorted out the problem myself, I fixed it up in FCP, which I think I read somewhere in one of the forums, but was hoping to fix it directly in DVDSP.
Anyway I just imported the aiff file into FCP, faded up the beginning and faded down the end, then exported that file back to DVDSP and no longer was there an audio glitch. It’s strange though, because the actual loop I used already faded in and out (before I even adjusted it in FCP) so I didn’t think I would need to fade it in and out in FCP, but anyway that fixed the problem.
