Portable TV with video out? (or how to make)

I'm going on a world-trip in a few months, and in that respect I'm
curious as to what each country is showing on TV. In addition it would
be great to actually record some of it to videotape (my camcorder has
video/audio in connectors).

A handheld TV would be ideal for this, but the question is if there are
any around which has a video out jack? It seems that at least the Casio
models I've checked out only have video IN, so as to let you view video
etc. on the TV screen.

Alternatively, could an old VCR unit be modified for this use, taking
out the tuner part, making it battery-driven etc.)? I actually have a
damaged (the mechanics that is) VCR, but although it seems like a good
idea I wouldn't know how to handle the actual tuning as it's based on
the remote control and not a simple knob.

Could a portable TV be easily modified for getting a video out jack?

As I'm in Europe (and most of the Asian countries I'm visiting, with the
exception of Japan) uses PAL, the tuner or TV has to be PAL as well.
(I guess it's not possible to get hold of a tuner which handles NTSC as
well as PAL, or a converter which allows NTSC singals to be converted to
PAL, for recording with my video camera?).

Note that there are about half a dozen variations on "PAL", mostly being
differences in things like sound carrier frequency...
Do not assume that a PAL tuner will work correctly everywhere.

1. PAL is a video standard...it has no direct connection with broadcast
frequencies (channels) world-wide. Any given hand-held TV receiver you buy
locally may or may not receive both picture and sound in the various countries
you intend to visit because, PAL or not, the local stations may broadcast on
frequencies your receiver cannot receive...and with sound mixed with picture in
ways your receiver cannot decode.

2. I have an early Casio portable (4" screen)...don't keep it here so I don't
remember the model. It has an "AV" socket through which video can be input and
output with the special cable the came with the unit. So they do (did?) exist.

3. Although nothing is impossible, modifying a table-top VCR tuner (and the
associated demodulating circuitry) to handle different signal standards (PAL,
SECAM, NTSC) and different channel assignments (frequencies) and different
audio modulation schemes...is not going to be easy.

4. There are (search the www) standards-converting boxes (SVGA-PAL-SECAM-NTSC)
out there. Your camcorder may or (more likely) may not record any video
standard with which it is presented at line levels, so you will need a
standards converter if it does not. My converter cost about US$200 from a Hong
Kong business, and runs on 12 volts DC. It works about the same as my Samsung
all-standards table-top VHS VCR...except that it converts to-from computer SVGA
also. (The Samsung does not).

Yes, I know about the different audio formats of PAL, such as the
greater part of Europe vs. Hong Kong/UK, but I believe that some systems
have switches which allow you to use the same TV in those different
countries.
