Hello All

I'm in the US and I have a Cyberhome DVD player - it's region-free, but that
is incidental to my question.

1) When I play a PAL DVD from the UK or Australia my DVD player reads the
PAL encoded DVD but outputs an NTSC signal - to allow my TV to correctly
display the picture. All is good except that the picture can be a little
jerky if there is fast movement - I assume that this is part of the frame
dropping that occurs during the conversion.

2) I also have an external video standards converter - a TenLab TR21 - that
will convert a PAL signal to NTSC. If I play a PAL DVD and output PAL from
the DVD and run it through the video standards converter and output an NTSC
signal to the TV the picture is also fine - perhaps of marginally poorer
quality than in (1) above, but not jerky.

Can someone explain to me what is different between the two ways of getting
an NTSC signal to the TV from the DVD and why the difference in jerkiness
and clarity?

Thanks!
