Hi - I just got a Sharp MD-MT15 unit, and am having problems with editing discs. Whenever I try to write out a Table Of Contents (after having recorded or deleted a track on an MD), it displays "UTOC ERROR" message, and doesn't complete the edit. This happens with MD's with material on them already, and also on totally blank discs. I got this on eBay, without a manual. The seller said he hadn't seen that problem, but hadn't used the thing in months. Sharp customer support said it may need service, but the nearest service center is 400 miles away. Am I missing a step, or need to know some voodoo? Or is it most likely broken in some way? thanks jeffj pegasusgiraffe@hotmail.com
