The DVD will work on a PC, the PAL format isn't the problem its the region code.
To change the region on you computers DVD Drive (you can change it only a limited number of times);
If you're running XP just go to 'My Computer', right click the DVD Drive (D:) for example and select properties, select the hardware tab and then select the DVD drive from the list then select properties again. Select the DVD region Tab and then select the United Kingdom from the list then press OK. This will now select the DVD drive to Region 2 (UK) rather than Region 1 (US).
Something like PowerDVD will then be able to play the disk.
You can then re-encode the PAL video standard to NTSC video standard but will lose some video quality. If your television is an HD flat panel, connect your PC up to the TV using a DVI to HDMI cable for the best video picture quality. (You may need the latest Graphics Display Card Drivers though).

Or you could always purchase a multiregion DVD player with an HDMI output.
