Page 1 of Newbie Question re Goodmans 285DPL

Hi there, I am quite ne to this home cinema stuff so forgive me if I am going over previously stated stuff, I could`nt find anything in the FAQ so I guess this is my best shot.
I have a Goodmans 285DPL tv and the Wharfdale 750 DVD player from Tescos.
My problem is as follows, I can`t play any discs that are in the NTSC format. Regional encoding is not a problem as I have used the mutli region hack and played back a region 1 DVD perfectly on my portable TV. I have also tried a region 0 NTSC disc but this also fails to work. Whenever I try to switch display modes through the Wharfdale the screen seems to lose its vertical hold and/or go black and white which leads me to beleive the problem lies with the Goodmans 285DPL TV. The TV manual states that the set has been locked to PAL mode but surely the Wharfdale player should get around this thanks to the PAL option it has in the display menu?
Failing that does anyone know of a way to unlock the Goddmans 285DPL so that an NTSC sign can be displayed as it seems unlikely that Goodmans would manufacture a completely different TV for sale in Europe and America?
Thanks in advance,
Kris.
