Hello. I always use DVDD to create iso and Imgburn to burn mds file for my Verbatim DL burns. I don't have any DVD, so I often use DVDFab to rip movies that DVDD can't handle. To burn these onto DL, I just use Imgtool to create an iso file and then burn with Imgburn. Doesn't create an mds file, but have yet to have a single problem yet with either method.Samsung SyncMaster 940BW 19" Widescreen Monitor via DVI, Coolermaster Centurion 5 case, Thermaltake 480 watt ps, Chaintech mobo, AMD Athlon 64 FX-55 San Diego Core @ 2.86 Ghz, XFX GeForce 6600GT AGP, 1 GB Kingston Hyper X PC3200 Dual Channel, 2x250 gig WD SATA, Soundblaster Audigy 4 soundcard, Sony DDU1615 (patched to Lite-On 16P1S) for ripping, NEC 3520A for burningEncoder vs. Transcoder results
