I've made a few backups using both DVDDeecrypter and DVDShrink over the past few months and on occassion I've run into a problem where about halfway through the movie backup disk it will freeze on me when playing in my Toshiba stand alone or some have just begun to skip and pixilate for awhile then straighten out. I'm wondering what are some issues that could cause this. I've been using Verbatim Dual Layer disks which can be pretty pricey to have bad burns with. My burner is a Sony DRU-710A. I'm pretty sure I've been burning at 2.4x on the Verbatim DVD+R Dual Layer disks.
