That looks to me like you're trying to copy a DRM'ed DVD.  Many 
commercial DVD's are created in such a way that reading them with a 
computer DVD drive results in errors, providing a sort of 
copy-protection--the only trade off being that doing so requires 
violating the DVD spec (where content owners don't seem to be concerned 
by such trivial matters as specifications).  Myth has no support for 
copying such DVD's--it aborts when a disk read error occurs.

So, what you have likely isn't a valid DVD--it's a RipGuard or ARccOS or 
whatever abomination.
