Philips HTS3500S DVD Region Hack

Hi to one and all,

Not sure if this is the right forum to ask the question? If not I apologize.

I have just brought the above Home Theatre system and am wondering if any one knows of a way to change the region setting so it accepts all regions.

I am in the forces and due to various postings overseas have a multitude of different dvd's in various regions.

Regards

Opalman
