Hi there,

Thanks for the quick response.

The source is a pal dvd with a regular 5.1DD soundtrack. What does the 
mc setting actually do and do you know what actually causes this problem?

I did try another disc and for what I saw it didn't have this problem 
although the disc in question takes until 9% of the first pass before 
the error pops up, this goes on for a few minutes where it's stops only 
to start up a short while later.

Thanks again

Dom
