I am using windows 2000 with a LiteOn 16X DVD-R/+RW and using RiDATA 4X DVD-R disc. Trying to burn a movie. After the burn I receive the following error --- 9.36 35 Burn completed successfully @ 4x 5520 ks 9.36 35 Verification started 9.37 31Cannot mount the written CD LiteOn DVDRW Sohw-16335" (H1. T.1) 9.37 31 Data verification failed Burned the same movie in another machine running XP, same type disc but in a Pioneer 4X DVD/CD writer. Had no problem and burn and verification successful. Whatam I doing wrong with the LiteOn burner?
