Frame rate on DVDs

1977jmp

Hi guys

Hoping somebody can help me with a technical question regarding the frame rate on a playback of a DVD.

I regularly buy discs of football games off a guy in Britain. Over the years 99% of these discs have been fine. However, some of the more recent discs he's sent me are suffering from a particular problem.

Basically, the footage plays as if it's had half the frames removed, and plays steadily but jerkily, as if it's a movie rather than a recording of a live-coverage football match (if you see what I mean). The actual image quality is fine, i.e. everything is pin sharp. But the frame rate makes it look like something from the 1950s.

I've changed my DVD player and tried a few different TV sets, but the problem remains with these particular discs.

The guy is extremely helpful to deal with, but he can't understand what's wrong, and he says none of his other customers have said anything to him about this.

So, anyone got any ideas? Is he unwittingly compressing the files too small when he's burning them to disc himself? And then the ultimate result is this jerky quality to the flow of the footage?

Many thanks to anybody who can help with this, it's driving me mad.
