Scripting Issues using Blu-Ray Player

I've been working on a rather large project for quite some time now and I've tons of scripts, menus and tracks. I did testing on the DVDSP simulator and on a SD DVD player and both worked fine.

Then I tried testing it (SD DVD) on a Blu-Ray Player and there seems to be a wrong jump. It appears to me that SPRM 4 and 7 reset their values to 1. Do Blu-Ray players read scripts differently? Has anyone else had this problem? Any help is appreciated!
