I've found that BLU-RAY.com does not work on any Title (Die Hard, Dune...). It could be an issue with "Region 1" since that's where I am and I've seen other script issues that were Region based.
At any rate I've tried with the above Titles one at a time as well as within Chains and it always fails. No modifications to have been made to the Script or the user configurable parameters.
