I recently had to rebuild my computer. New motherboard, power supply, and hard drive. All is back together now and working fine except for this issue. I normaly used WMP to play a DVD before backing it up. Now the play back of the ORIGINAL disk looks grainy or mottled. Hard to describe, but it looks poor. I make my back up in the usual manner and it (the Backup) looks great. I am puzzled. Using all my usual tools and settings (as far as I can recall). Disks are Sony +R MIJ (TY) with ImgBurn performing the final processing, booktyped to ROM. I have selected burning at 4x on the 8x disks, but it burns at 1.2 anyway. So it takes a bit longer. Yes, DMA is ON. Wonder what might be causing the slow down? Any ideas on what I may be missing? And why would the copy play BETTER than the original?
