Well i started making copies of my dvd's using my plextor 740 and the made in singapore 10 pack verbatim dl's. However out of the 10 pack 1 was a coaster (it didnt finish burning had a write error). 1 completed burning however my dvd player, ps2, dvd burner, and dvd-rom will not read it. and 1 glitches in the beginning of the movie. The other 7 are perfect (as well as i can tell i only watched the first 5 min and skipped thru the rest). Is this normal? lol at 2 bux a pop i can deal with, but with only 7/10 burning correctly its costing me even more. Could it be because i burned them back to back? maybe overheating??? I use only dvd decrypter to read/write.
