Just read another thread saying Gladiator is cut for R2 which I didn`t realise.
When films are cut for R2 is it a different version than what was screened in the cinema in the UK or do the same cuts take place there as well

R2 Gladiator isn`t cut. People are assuming this because of the different NTSC and PAL running times. Check www.dvdcompare.org.uk for peace of mind.

IS a second of PAL video somehow different than a NTSC second ( I thought the measure of time was uniform across the planet?)

I am not totally sure how a film can be the same and have to different running times, but it has got something to do with the fps of NTSC and PAL. NTSC runs at 30fps while PAL runs at 24fps. This means that a PAL movie will be slightly shorter due to it having less frames per second - about 4% I beleive.
I hope that this is correct, if it isn`t then can someone please correct me :-p.

Sound right PiKL
Film is at 24fps
NTSC is at 30fps. Film->NTSC by repeating 6 frames a second.
PAL is at 25fps Film->PAL by 4% speedup
So NTSC runs at correct speed, slight judder can be seen in camera pans due to the repeated frames. So runtime is the same as Film.
PAL runs 4% faster so PAL, this leads to slight pitch shift in the audio, runtime is 4% shorter than NTSC

I`m confused (so what`s new?!)
If PAL runs at less fps - shouldn`t a PAL film last longer rather than shorter?

A film is 100 frames.
PAL runs at 10 per sec, NTSC at 20.
100/20 = 5 secs.
100/10 = 10 secs.
The PAL one takes longer to run. Haven`t they got round to sums in school yet? ;^)

OK PAL = 25 frames per second ( 1 second of video ) NTSC = 30 frames per second ( 1 second of video )
So unless your dvd player is counting frames the running time should be equal between PAL and NTSC DVD`s ( assuming no cuts have been made)

No, that`s not right,
PAL 25 fps NTSC 24 fps
If NTSC had more frames per second the films would be shorter than on PAL.

ARRRGGHHHHHHH!
Look
Read the FAQs guys, it`s all there.
From rec.video.dvd faq...."Coded frame rates of 24 fps progressive from film, 25 fps interlaced from PAL video, and 29.97 fps interlaced from NTSC video are typical. MPEG-2 progressive_sequence is not allowed, but interlaced sequences can contain progressive pictures and progressive macroblocks. In the case of 24 fps source, the encoder embeds MPEG-2 repeat_first_field flags into the video stream to make the decoder either perform 2-3 pulldown for 60Hz (59.94) displays or 2-2 pulldown (with resulting 4% speedup) for 50Hz displays. In other words, the player doesn`t really "know" what the encoded rate is, it simply follows the MPEG-2 encoder`s instructions to produce the predetermined display rate of 25 fps or 29.97 fps......"
