I had been burning dvd's no problem, but one day I got a "sector 0 unreadable : verifcation failed" message during verification. When I tested the disc it didn't work at all, I have since tried many times to burn a disc but none have worked. If I do verification, it fails, and the disc doesn't work, if I don't, the disc also doesn't work then. I changed my Recorder settings to put BUffer underrun protection on, not knowing if it would help, and it didn't. Every time I try and burn a dvd now, I have this problem. Any help would be greatly appreciated.
