Hey,
I was trying to copy a home dvd, and disc utility showed a message that said that it was unable to copy image, input/output error. What does this mean?
the movie was made with a vcr to dvd recorder. It is on a dvd-rw. I put the disc in and everything started fine. disc utility began to copy the image, but about 5-10 minutes into it, it promted me with the forementioned message.
I have just approached the situation using handbrake. I was able to extract 1/2 the dvd, considering the dvd consists of two segments. I am however, unable to successfully extract the second segment: which will rip only 4.23% of the segment. Very odd. I can copy other dvd's and play them. I can also play the one I want to burn.
Does the DVD have a folder named "SONATA" by any chance? Some recorders encrypt the recorded video (Sony, LG are a couple that might use it). The only way I was able to copy or otherwise use the VOB was to use DVDFabDecrypter, which runs on Windows.
If there's a VIDEO_TS folder on the root of the DVD, you can open the various segments and copy the ones you'd like. The DVD might be ecrypted, as gr8tfly said, and that would make ripping the DVD a pain.
