Its strange how US players and TV's can't play PAL material. It would be hard to find a TV or DVD player here in Australia that doesnt support NTSC. Even an old TV I have works fine with ntsc, the old video player doesnt player NTSC just comes out black and white. The new video player does though, but it doesnt record in NTSC. Why do they have to use NTSC in the US, just to complicate things! wouldnt it be easier if there was only PAL? You Americans love being different with your 100-120v electricity system too!
Ok, there are several questions here
Most PAL video players and DVD players can play NTSC tapes, correct. However, they don't output 'pure' NTSC - instead, they output a hybrid signal called PAL60. (Some high-end players can be set to output pure NTSC as well.) This signal is essentially the same timing as NTSC, but uses PAL colour encoding, and is supported by pretty much any TV built in the last 10-15 years. The reason you're seeing a B&W with the equipment you mention is because it does not fully support NTSC recordings, and so cannot decode the colour part of the signal. No PAL video recorder is capable of recording in NTSC - for that you would need a multi-standard deck (which will of course output pure NTSC if required).
The reason for all of this is that there is a high demand in Europe/Australia/etc for American videos (and these days, DVDs), so it's worth the manufacturers' while to support playback. There is virtually no demand in the US for non-US tapes and discs, hence hardly any US TVs support a PAL signal. In order to play a PAL disc or tape in a US machine, the machine has to have a full-blown PAL->NTSC converter built-in so that the output signal is pure NTSC. These are not cheap and, as there is little demand, very very few machines have them.
NTSC pre-dates PAL by a good few years. PAL was actually developed to fix some rather nasty problems encountered with NTSC (which NTSC suffers from to this day, btw ;-). It is by far the superior system, although it has its own set of flaws.
