Guys
I have come accross a problem with my father-in-laws DVD player.

The problem seems to relate to the format that the DVD is encoded
under. If He plays a PAL encoded DVD then all is OK. If he plays an
NTSC encoded DVD then the picture rolls. Colour is OK so it's PAL
encoded, and he can flick a switch under the front panel of his TV
that changes it to 60Hz fields - and everything comes right again.
(Untill he goes back to off air or the flash screen of the player
etc.)
The problem is that he doesn't want to. 

I know my TV automatically adjusts between various formats but have
not been able to figure out if the field rate is changing or if my
VCR/DVD player does the conversion. I could dig the 'scope out of the
garage but was looking for enlightened opinion first.

Is the 50/60Hz field thing embedded in the DVD data, or is there a
chance he will be able to buy a new DVD player (at reasonable price)
that outputs standard PAL 50Hz whatever the encoding?
