importing dvd's into mythtv

I'm having a bit more success with importing some dvd's into mythtv, but the 'bad sector' copy protection is painful. dd_rescue allows me to make an image but the deliberate bad sectors turns a 30 minute process into a 1 hour 30 minute process as reading bad sectors is terribly slow. The bad sectors are almost always going to be in a chunk (512 sectors for the Toy Story 3 DVD I'm importing now) so I was wondering if there exists an application to do it a bit smarter, eg if you get 4 bad sectors in a row, jump forward some small number of sectors (eg 64) and keep doing that until a good sector is found, then work backwards to the last bad sector, and then assume that the sectors inbetween are bad. That would dramatically speed up the process... Does such an app exists? Or failing that, a way to make the DVD drive not spend excessive time trying to read corrupt sectors and let the application re-read if it thinks it needs to? I could simply rip the movie out but that requires more effort than I'm prepared to commit to the process (finding the movie file is increasingly difficult as modern dvd's contain phantom files of similar sizes) and I value my time more than I do the $$$ required to store the raw iso's. And the kids enjoy the little dvd games too. Mainly I want to avoid the piles of DVD's that never seem to get put away :) James

Yes, search for "bittorrent" in your package manager ;)
