Field matching without Telecide?

[DJ Bobo]

I have an Anime PAL DVD which was thanks god speeded up to 25fps. But the fields are somehow not in the right order, that's why I use Telecide to get a clean output.
Is there a way to get the same effect as Telecide but with basic AviSynth functions? (to get more speed)

[EDIT]
I got it already:

ComplementParity
DoubleWeave
SelectOdd

But no real speed increase, only 4% faster.
Well, seems like Telecide is already optimized enough...

There's also SwapFields(), which is actually internally implemented as the 3-line chain you found. Decomb is definitely fast, though, no argument there.

No, SwapFields doesn't work on the DVD I have at all (if it was that easy, I would already have checked it in DVD2AVI ;))
It doesn't work because the fields were inverted (that's why ComplementParity) and the first field (which was second field before ComplementParity) had to be ignored (that's why SelectOdd and not SelectEven)

Seems like Telecide is better anyway, since there was a small part on the DVD where the fields were inverted again, so I got interlaced output on that small part. Telecide has the ability to adapt whereever there is a change in the field order.
