Not very well. To fully understand why, you need to understand the main difference in PAL and NTSC TV standards. First understand that the PAL/NTSC are Television standards. PCs do not apply. So you can burn a DVD using NTSC (in Boston) and play it on a PC in England (PAL). No affect at all.
PAL
1. Frame sizes of 720 x
576
2. Frame Rate of 25 fps
NTSC
1. Frame sizes of 720 x
480
2. Frame Rate of 29.97fps.
So with that said, to convert a PAL video to NTSC, the program needs to create, ie; make up just shy of 5 frames for every second of video,
AND decrease each Frame size about 96 pixels on the height.
According to Steve the electricity in your wall outlets, in England pulse at a rate of 50 cycles per second (50Hz) where here in the US (NTSC) it pulses at 60 cycles per second (60Hz).
There are some programs that claim to be able to convert them. How good a job they do is unknown to me.
You could try a free program called
DV Date by Paul Glagla. Nice free, very light weight application, that not only will allow seeing the date/timecode and burning to your video, but claims to be able to convert to a few other formats, and the NTSC-PAL conversion is one.
For converting your video from one format to almost any other, try
SUPER. It can convert DivX, Xvid or even MPEG4 files.
Finally I will add that several members have posted, many current DVD players can play either NTSC or PAL. In fact they claim for years that the PAL DVD players have been able to play NTSC, and that only within the last year or two, NTSC players have started doing the same.
