Interlaced film?!

[Floatingshed]

I recently bought the DVD of "The invaders" and decided to make AVI's to watch on the laptop. Usually I would put 'em through Telecide and decimate and get lovely 23.97 progressive frames, not this time! With this DVD every frame seems to be interlaced although the source is film. This has me puzzled, any help much appreciated.

Here's a sample: http://www.mediafire.com/?czwqljxmmyj

Seems a fieldblended standard conversion to me. Probably they've made a PAL to NTSC standard conversion.

That's certainly how it appears but this is a region 1 DVD!
Why would they make a PAL master of a US show and convert it for a US release?

possible bootleg ?

Where was it purchased?

Happens all the time. They take an already existing 25fps PAL master and run it through a cheap standards converter box. It saves the cost of creating a proper NTSC master. The fix is to unblend it:

One of the most common reasons to do this is the music background, sometimes the EU (PAL) versions have the original music, while the US releases on DVD might have a reworked sound (licences, copyright).

Amazon (not marketplace), I believe that it is genuine. It must simply be cost-cutting as Manono suggests.
Srestore does fix it nicely. Thanks all.
