Update. After installing from Beta (great work guys!) still have the skip. I mapped a drive from the NAS on my XP laptop to look at all files on the drive and found 16,572 CHECK_MOUNTED files that were being added by the core every three minutes, as well as files from DVD's that didn't rip successfully, in a folder called trashbox. I deleted all the files and then disabled Read/Write access to the drive and, NO SKIP! I know this may just be a temp fix but finally no skip.
