here is something interesting-
the major studio hollywood films were backed up with no problem. The smaller independent dvds burned the menu screen and nothing else. I own all these and tried a few different times.
Secondly, my computer's dvd burner was set at the 8x default. Could this be a result of using 4x dvds burned at 8x speed- about 80% failure rate?
I tried burning at 2x last night. DVD failed on my toshiba home dvd player but worked on my laptop dvd player. I re-dvdshrank everything to try again. Could this be a toshiba dvd player issue? Is this a common problem?
This isn't a dvd-r vs dvd+r issue, is it?
I believe now it has to be the media because my attempts with 10 dvd-rs proved to be fine. What's weird is that I'm burning home video using a vhs-to-dvd recorder with the same media with zero errors- burned 25 dvds that way and never noticed a problem.
thanks for all the help, but as for now, I'm still searching.
