It means to set/assign General Parameter Register 0 to a constant value of 0. There are 16 GPregs available, GPreg 0 to 15. GPregs may also be referred to a GPRMs or General PaRaMeters. If you have done any software programming, it's easy to understand the logic.


Here's a good site to help you out on this command and many more. ;)

IfoEdit can be hard at times with more complex commands but you can still do it by hexediting. Of course, it's not as simple to newbies. But you're in luck, there's PgcEdit (http://home.tiscali.be/debie.roland/pgcedit/index.html) to make command editing easy. Load your DVD, select your PGC in PGC Selection list on the left, and double-click your line, in question, in PGC Command Table. ;)

Let's make this simple. GPReg(General Parameter Register) is the same as GPRM (General PaRaMeter Register)and vice versa.

Ifoedit and PgcEdit are two programs developed by two different authors. IfoEdit's author, Derrow, chose to use GPReg in his tool while rolZ, PgcEdit's author, chose to use GPRM. The acronyms are different but they are basically the same. In the DVD authoring world, GPRM is normally used.

Again, from the same site, here's a great page to read on GPRMs. http://www.dvd-replica.com/DVD/gprm.php

I highly recommend you check this site out as you can learn alot of how the DVD structure is and other essential stuff. ;)
