IIRC this is a problem caused by the copy protection breaking libdvdread. I fixed this problem for this DVD by hacking libdvdread, there is a range check in the libdvdread code that causes it to abort reading the disk. The fix was to remove the range check, what I did was to keep the range check but just before the check was to set the the value to value = value % range. It then played fine. For a comparison I copied the DVD to the hard disk using AnyDVD and checked what mminfo said for the image and the DVD. The difference was that AnyDVD chopped of the data at the bad point whereas fiddling with the range check simply set this value to 0.
