I have a Phililps DVD (HDRW720) how can i make this regions free ?

I haven't had any experience with that particular model, but hopefully you can find some answers here:

Not sure, but I am in the market for a dvd player so am just posting here in order to subscribe to this one to see where it goes.

That model doesn't seem to be listed under either the hack section or the review section. Is it a new model? You might have to wait a while for it to be posted, if it can be done.
