Hello. I must first say that I am not expert to this but I have burned quite a few Dvd’s with a Sony Dru510A. It would burn my movies and discs and 4x and take a total of 16:08 for a full disk. I thought it might be nice to get something a little faster and move up to the dual layer so I went to Best Buy and bought the Plextor 716A. Now after reading a lot of bad posts, maybe I bought the wrong drive? This is what Ive done and I would appreciate any input. First I have a Pentium 4 3.0 with 1 gig of ram. Windows saw the drive and installed it, no problems there. I have some TY disks that are rated at 8X so I tried one of them. It gave me the option to burn at 16x so I figured what the heck and tried it. Writing the lead in it really moved but when it changed to data, it slowed down. The disk took 12:30 minutes to burn which is not 8x or 16x but is faster the what my Sony used to do. Then I tried a 16x rated disk that came with the drive. It burned a full disk at 7:52 which is much better but seems closer to 8x then 16x as the disk said. I went to best buy and bought a pack of Verbatim rated up to 16x and tried one of those. They burn a full disk at 10:24. Every disk I tried has given me the option to burn at 16x. Im using nero. I set the jumper on the drive at cable select and it choose master. I do have another dvd drive on the same cable, could that make a difference? I did not use them both at once. Is there a setting im missing? Im set at ultra dma 2. When nero gets done burning it says burn process completed at 16x but the times sure dont reflect that. The times are not bad but they are not close to what the should be. Did I get a bad drive like a lot of other people? Please guys, any help is appreciated. Thanks.
