PS I do know that there are US spec DVD players that can play PAL DVDs

that special players are not required.
I'd be surprised if there are ANY U.S. players that CANNOT
play PAL still being made. Also, the usual path from PAL
to NTSC is to slow the video and audio down and make it
24 fps... Hard telecine is usually considered BAD, and it
also is really impossible to go from 25 to 30 fps directly
anyway, the result will always be crap.
The Pioneer DVD recorder that I use to record the PAL input is one
that will not play UK PAL onto an NTSC TV. It will play NTSC on a PAL
TV, but not the other way round.
Surely the frame rate conversion issue is the same whether the
translator is inside the DVD player's hardware or within transcode.
Even the hardware decoder will have to decide which frame of the 25fps
interlaced source to play at the 29.997fps rate. I would have thought
that the result from a well configured transcode conversion should be
as good as a hardware conversion. The only loss would be if
requantization was required to make it fit on a single-layer DVD.
That said, if the source is quite poor, the result of the
commands you are using may look fine in comparison. But
if you use those commands on a high-quality PAL dvd the
result will be quite poor, with lots of stuttering and
jumpiness.
The video result from my transcode command is fairly decent, with no
noticeable jumpiness. The only problem is that the audio, though
playable via dragon player as an MPG, doesn't survive the makedvd
command
Your transcode command has confused and incorrect audio
options. Please search the wiki for "ac3" to see examples
of how to pass through ac3 audio.
I'm having trouble finding anything in the transcode wiki on ac3
conversion. Can you give me some clues as to which specific command
options are incorrect, or point me to the specific examples that you
are citing?
Thanks
