Hi All, Recently, dvd's burnt using liteon 811s, they come up with error message "UNRECOVERED READ ERROR (031100)". Liteon 811s dvd write, windows 2000 sp 4, using nero , dvd santa software to burn. Burning phase is without errors. But reading same dvd doesn't read either in dvd-rom drive or same dvd writer drive. I have burnt lots(100's) of dvd's before. Recently this problem started happening. Tried burning at 2x, 2.4x, 4x and 8x, all results in same problem. Sure it is not problem with media because both the media's i am using for a long time and they were working fine until this problem started. Thanks for your help/advice in advance.
