Oh also, as a note to nitpick ... lcd and plasma displays have physically fixed pixels and unlike crt technically cannot change resolution. What this means is that for a PAL monitor you have 576 lines ... for an NTSC monitor you only have 480 lines .... SO, if you're going to play a PAL DVD on an NTSC lcd or plasma TV then the picture is resized from pal resolution to pseudo-ntsc resolution at 25fps. Likewise if you're going to play an NTSC DVD on a PAL lcd or plasma TV, then the picture is resized into pseudo pal resolution as it cannot be displayed in its native resolution.
These limitations do not apply to CRT.
Also all yanks be thankful you have the MPAA. We have a crummy sheep of an O.F.L.C. that plagiarizes classifications from Australia and Great Britain! At least yours makes up their own minds.
