Hi Mark,

That was quick, I didn't even finish the movie :) This is the output:

Although the error seems to be caused by reading from DVD. The DVD is 
brand new, no visible scratch or anything and no error output in Linux. 
(Which you would expect if it was a medium error)

I doubt it is related to a corrupted medium or corrupted stream. How could 
we debug this further. Is it libdvdread ? Should I address another forum ?

Thanks in advance :)
