I am using Ridata 2.4x DVD +R DL disks and am having burning problems. I seem to only get about one burn in every 3 or 4 attempts. Am using variety of programs--Nero, CloneDVD2, DVD Shrink, DVD Decrypter in various combinations to rip and burn. There does not seem to be a pattern. Very frustrating not to mention wasted disks. Have tried burning at 2x and 1x---same problems. My equipment is a Sony Vario R--lots of available memory and RAM. Any suggestions? Thanks.
