I copied a Tivo recording to a DVD-RW using a LiteOn recorder. I played it back to test it and it was okay. I loaded it on my mac -- same thing. Then I used MacTheRipper to transfer the image to the HD for further processing. During the transfer, MRT said two VOBs had "intentionally" bad sectors; I padded them. This happened twice, so I don't think it was a bad DVD-RW. MRT said the resulting image might not play. Once I had the transfer done I used myDVDEdit to modify it and tested it with iDVD. It hung around the point where the padding would have occurred. I can see how this might happen with a digital recording, but the transfer was 480i over a composite line with S-Video. How is that possible and what do I need to do about it? The show I was trying to transfer to DVD is playing again later this month and I am going to record it again in case the problem is somehow with the original recording. However, I am at a loss as to why the Tivo and DVD copy would play with no problem while the transfer has problems.
