And, really, the best place to discuss the issue is some forum for some
dedicated DVD-ripping software, rather than here.
The only thing of importance when it comes to MythTV is that MythTV has
no code to try to work around broken/non-compliant discs or any kinds of
copy protection, including structure protection. So, whatever you do,
you'll need to get a good video without any of the garbage or MythTV
probably won't be able to play it properly.
