As I mentioned I tried the DVD in the laptop drive and the player locks at the “spot”
I then tried to copy the vob’s to the computers harddrive and I got a read error 1/2 way thru the 3rd vob.
In my opinion this verifies what I have been thinking. My belief has been that the disc has a marginal spot and that better players with faster drivers were able to try it enough times to get a good read.
If I’m wrong tell me and let me know how to proced.
