I have a toshiba sd-r5372 that I just recieved back from warranty work and it seems to work less than fair. Attempting to "back up" er to my hd, the program found the TOC on side a, but when I go to side b, its not able too, this happens with other dvd too. I took the disk and placed it in my laptop running the same program and it found the TOC first try. Is this sd-r5372 still messed up??
