Hi. I too have a Philips player (DVD957) and I used some of the temporary hacks available on these forums (try region hacks, over on the left column...) These hacks are limited to 25 times before they lock the player in the last region selected (as I found out to my dismay when it locked in region 1, especially as I didn`t own any!)
But if you buy an OneforAll remote (model no URC-7541, available from Argos @ £24.99) you can use a hack, which makes your player (in fact most Philips players) multiregion. This hack can be found here: http://www.dvd.reviewer.co.uk/info/multiregion/full/philips750.asp
Hope this helps.
