I used UDF 1.02 I used ImgBurn to copy the files. I captured my 1 hr 1min miniDV tapes with Adobe Premiere Elements as an .avi (approx 13GB) and then using Adobe, cut the file into three segments so as to have 3 files less than the 4.7 GB of a DVD. I saved each .avi file to my hard drive and then transfered the .avi files to disc via imgBurn. Some of the files were just a little too large when using the ISO9660 file system so in Options I disabled it and only used the UDF 1.02 file system. I would then use the Build option in ImgBurn to transfer files to disc.
My DVD drive never had a problem reading the UDF files only, until one day it just started reading only ISO9660 file system and not UDF. I've tried to update drivers, checked DMA settings, disabled and re-enabled the drive but none has changed anything. My best guess is it may have something to do with SP3.
