The last two DVDs I've burned have had errors at the tail end. It's only by chance that I caught the errors. I usually don't watch an entire back-up DVD after I burn it; I just spot check it by jumping forward to the start of each "chapter" and then watching a few seconds to see how it looks and sounds.
The two I burned today had severe skipping and freezing after the hour and thirty minute mark, so I'm wondering if the problem might be in the burner.
To be sure that the errors were not on the original disks, I played the original DVDs and they played fine in the same sections where the errors in the back-ups occurred.
The burner came from a patched together PC that an online acquaintance built for me from leftover parts, but which failed a few months after I received it. I bought a second hand Pentium 4 from my neighborhood computer shop and installed that burner in it.
I'm wondering if this problem of errors occurring at about the hour and thirty minute mark might be a clue as to the source of the problem. I'm thinking that it might be either bad disks or a bad burner.
I'd be grateful for some advice on trouble shooting the problem. I'm about due to order a new batch of blank DVD-Rs, so I could do a second burn of the same movies on a different brand of disk to see if that solves the problem.
Also, is there a program that can compare a burned DVD-R with the original DVD, to check for errors, so that I don't have to watch each of my back-ups from beginning to end to check for errors. Having to watch each back-up is too much like work, and takes the enjoyment out watching my movies.
I used DVD Shrink (via Nero) to burn one of the movies, And DVD Fab to burn the second one.
