Page 1 of Any info on Philips DVD640

I`ve looked at several players and have seen the DVD640 in Comet for £130. It seems to be okay feature-wise but can anyone tell me if it is possible to make it multi-region. (Another one I liked was the Samsung DVDS225 at £120 - any info on that ?)
And what does PAL/NTSC playback refer to and/or mean ?
I asked in-store but got the "oooohhh, I`m not sure" reply.
Sorry to ask so much so soon but I`m new to DVD so any info/help would be appreciated.

Thanks in advance.
Nige.

ps or can anyone suggest a better option, up to £150 ?
