NTSC or PAL DVD Disk???

[Myauk]

I am confused with video formats used for DVD Recorders and I need to
confirm my knowledge about them are correct or not.

A DVD recorder must have
1. Optical Drive for Play Back and Recording of DVD Discs
2. SCART, CVBS, Y/C, Y/Pb/Pr (interlaced/Pscan) outputs.
3. Tuner inputs
4. External DV in, Y/C in, CVBS, Y/C, Y/Pb/Pr, SCARTetc.

Let us say, I am tuing a RF modulated PAL-M channel with the tuner.
The signal is demodulated and sent to TV as SCART, CVBS, Y/C, or
Y/Pb/Pr for viewing. The output will be PAL signal, am I correct?
Then here comes recording to DVD-RW disc. So it will be recorded
digitally on DVD-RW encoded in some methods. Then the play back will be
PAL format, am I correct?
And Let us say, I have a PAL DVD Disc with a recorded Movie sold in the
market. Will it be possible to playback the disc with NTSC only
supported Recorder (like those in USA, not quite sure)?
My understanding is that if I play PAL DIsc, the out put will be in PAL
format, if I play NTSC disc, the output will be NTSC format, am I
correct??

It all depends on just what you mean by a "PAL signal."

Strictly speaking, "PAL" (Phase Alternation by Line, or similar
words to that same effect) is a method of color encoding, and
nothing more. "PAL-M" is a description of a broadcast system
which employs PAL color encoding but in a 6 MHz channel,
the 525/60 2:1 interlaced scan format, and the color subcarrier
at the "NTSC" typical 3.58 MHz. (This system is in use in
Brazil, but I don't believe it's a standard anywhere else.) "PAL"
is also (unfortunately) often misused to refer to the 625-line,
50 Hz, 2:1 interlaced scanning format common in European
(and elsewhere) TV broadcast (where the PAL encoding system
is commonly used), but it really is not strictly tied to that. (The
more complete description of those systems would be things
like "PAL-D," "PAL-G," "PAL-I," etc..)

Of the signals you mentioned above - well, some of them (a
"composite" video connection, for instance) could be considered
as carrying a "PAL" signal, as it would use that color encoding.
A YPbPr component connection might be carrying a video
signal at the 625/50 format, but would not strictly speaking be
"PAL" since the color-difference signals (Pb and Pr) are already
separated out.

Then here comes recording to DVD-RW disc. So it will be recorded
digitally on DVD-RW encoded in some methods. Then the play back will be
PAL format, am I correct?

Depends on how it was encoded onto the DVD and how it was
transcoded on playback. It might be PAL - it wouldn't HAVE
to be, in terms of the color encoding.

And Let us say, I have a PAL DVD Disc with a recorded Movie sold in the
market. Will it be possible to playback the disc with NTSC only
supported Recorder (like those in USA, not quite sure)?
My understanding is that if I play PAL DIsc, the out put will be in PAL
format, if I play NTSC disc, the output will be NTSC format, am I
correct??

The way most consumer DVD players work, that would be correct.
