Converting a signal from NTSC to PAL or from PAL to NTSC is a major
undertaking, and requires some sort of standards converter. These
(usually rather large) pieces of equipment cost thousands of dollars.
I work at Ampex, where we develop many types of professional video
equipment, and I've never seen a standards converter in our labs. They just
cost too much to have around.

Your Sony TV which will display both NTSC and PAL won't do you any good
unless you have a PAL VCR to play the tape with. The PAL and NTSC formats
are rather incompatible: NTSC is 525 lines per frame, 30 frames per second,
with a 2-frame color sequence. PAL is 625 lines per frame, 25 frames per
second, with a 4-frame color sequence. 

Because of these differences, the recorded tapes, and the VCR's are different.
