What are the main differences between PAL and NTSC?
PAL has a better resolution than NTSC (PAL has more lines). NTSC also has a problem in that it uses 29.97 frames per second, where most (if not all) films are shot in 24 frames (this can be solved with a process called 3:2 pulldown, but it creates problems [1]). PAL uses 25fps, meaning films actually run 4.2% faster on PAL; no additional techniques are needed here.

IIRC PAL is actually clocked at 50Hz interlaced (so is as if it was 25Hz - not all scanlines are drawn each cycle) and NTSC is something like 60Hz interlaced.
PAL has a higher resolution, but suffers from noticable flicker when compared to a US TV.
PAL is actually clocked at 60Hz (interlaced) in Brasil.
PAL I is used in the UK, PAL M moist of Europe. They are not compatible. The sound carrier is not the same and a PAL M broadcast will produce no sound on a PAL I TV.

Thom Holwerda,
Why would they send you a free TV monitor?
OSNews isn't exactly the best place to advertise for them, right?
I'm not real savy on TV technology like my father is but you seem to know what your talking about.
