I know somebody in the UK who has some Doctor Who episodes on DVD--
probably made on an incompatible region 2 DVD player. But even if they
were either region 0 or region 1 discs, would they still be incompatible
because of the PAL/NTSC differences?

Home recorded DVDs do not have region coding.

And all DVD players (in the UK certainly) can play back "PAL" or "NTSC"
discs.
