Thanks again to everyone for the helpful replies.
dean, the Sammy is unable to enter any of the HDMI settings without actually being in HDMI mode, so unfortunately it doesn't matter. As I've mentioned, I can get into the menu through scart, but without being activated in in HDMI mode itself, I'm unable to adjust digital settings.

I've just looked up at the specifications on the Philips web site. Now I know it may be wrong, but it only lists 640x480@60/72/75/85Hz; 800x600@56/60/72/75/85Hz; 1024x768@60HZ; 1280x768@60Hz; 720x576i (576i); 720x576p (576p) as supported resolutions. Also no mention if these are supported over DVI - with the DVI input being listed as PC only, it may be that video resolutions are not supported on the DVI input at all.
I don't know about the Samsung, but I suspect that it is trying to put out either 576p, 720p or 1080i of which only 576p is supported on the Philips. So even if the multiregion hack does remove HDCP, you are going to be limited to 576p or, 576i if the DVD player outputs this via HDMI - many do not.
And this is assuming that the multi region hack indeed removes HDCP.
If you do however get it working, you may then run into the additional problem that due to differences in DVI-PC and DVI-Video formats it may be impossible to correctly calibrate black and white so you may get a very grey 'black' and an off white 'white'. This will be a problem if you are sending DVI-Video levels when the TV is expecting DVI-PC levels.
Great stuff, ianh64, thanks for this.
To address your points, the Sammy is able to output 768 once hacked, and my Philips manual says that setting in DVI mode if connected to a PC should be "1024x768 @ 60Hz", so I know the DVI jack input and TV resolution is capable of 768.
I've managed to get the Sammy playing on my PC's LCD now, which is good news and it proves the Sammy's outputs are working and that the HDCP is disabled.
I've also managed to get a picture onto the TV now, but it's a bad picture at odd resolutions that only appears sporadically.
Touching on a point made by mike7, I managed to find the "Mode A" and "Mode B" settings while it was hooked up to the computer, but while it's hooked up to the TV, it doesn't have these options. The Samsung appears to know when the connected device is HDMI or DVI and switches accordingly, but can't do it when hooked up to the TV, which leads me to believe that the TV is not sending out a certain signal that the Samsung is searching for. When hooked up to the TV, the menu settings indicate that the Samsung thinks the device is HDMI, not DVI.
So not much luck all round, although it is odd that I'm managing to occasionally get a picture, albeit a poor and disfigured one.
Touching back on ianh64's point about "differences in DVI-PC and DVI-Video formats", I do not know the differences, but that was sort of my original point here, perhaps the Philips' DVI connection is never going to accept a DVI signal from anything other than PC. I have no idea why, without fully understanding the technology. I'd have thought there'd be one standard DVI signal, with the only addition being HDCP encryption, but my Philips appears to be proving me very wrong here.
On a positive note, it looks great hooked up to the PC through DVI. Heh.
