( Rant about Quicktime, iTunes and Apple and them messing up me playing MYST )

Does anyone know how/where one can change the dvd player on a labtop to a multiregional one?

Cause I have DVDs from the UK and the US and I wish to be able to see both of them.

For basic info: I have a Toshiba.
The DVD drive is: TSSTcorp CDDVDW TS-L632H ATA

So....Help????!!!!
