I have 2 Xboxes. One of them is a 1.5 and was modded by a friend of mine. The other one is a 1.6 and was modded by me last month. I never really played many backup games off of disc on the 1.5 box up until recently. I'm noticing that the DVD drive in the 1.5 unit is WAY more picky about the DVD media being used. It usually recognizes Memorex DVD+R media, but even sometimes has a problem with those. The DVD drive in the 1.6 unit will pretty much recognize any DVD+R I use (Maxell, Verbatim, Memorex). I have had no problems yet with this drive. Is there something I can do to the older DVD drive to try to get it to recognize more types of media ? I read something about adjusting the potentiometer in the DVD drives. Could this help the drive with the other media ? The only other thing I can think of is to get a new DVD drive and/or Xbox and put a different DVD drive in the 1.5 unit. Any suggestions ?
