If I am backing up lots of .jpg files to DVD, what file system should I use? Would UDF 1.02 work fine, or would I be better off choosing something like ISO9660+Joliet+UDF so it was supported by everything (or does that cause it to be less 'stable')?

Ok, so it is not just a whole bunch of bad burns, but my drive just can't scan well. I had one more question, then me and my stupidity will go away. When I flip over a burned disk, disks that were burned at a speed greater than 2x seem to have a "darker circle" in the dye near the center while disks burned at 2x speed have even dye color across the back of the disk. Is this anything to worry about? Looking at the burn speed graph I posted above (first image), is this caused by the jump in burn speed at about the 250 mb mark? Here are two pictures for comparison. The darker circle is kind of hard to make out, but is on the disk in the first picture and the second picture doesn't have it.

I have a Toshiba Satellite A305-S6858 that has a Pioneer PIONEER DVD-RW DVRKD08L (ATA) with Firmware v2.51 (Toshiba hasn't really released any information about the firmware, which kind of stinks because I can't change the booktype of DVD+R to DVD-R, so I usually just get DVD-R disks). I recently thought I would scan a few DVD's that I had burned, but everything comes out with a 0% quality rating. These disks seem to read just fine, and the disks I burned a year and a half ago right after I bought the laptop still seem to work just fine. Below are some images from a disk I burned today. I know that this is cheap media (a TDK DVD+R 1-16x speed, CMC MAG-M01-00), so I wouldn't expect a very high rating, but everything seems to come out at 0%. I have tried Memorex, Imation (RITEKF1), Verbatim (I have some new MCC 03RG20) and they all come out to 0%. The burn speed doesn't matter either. I have tried 2x, 2.4x, 4x, 6x, 8x (can't burn higher than this because it is a laptop slimline drive). What I am most confused about is not the fact that it is 0%, but if it is 0%, how come the disk still works fine? I never get any errors opening files or watching movie clips. Some of these disks have burned home DVD movies on and they seem to work in players just fine, no skipping or anything. Log of the burn - Test Images -
