Been reading about how you take a NTSC interlaced video and turn it back to its source with Inverse Telecine. Is there any way to do this with PAL?

In short, no. NTSC is telecined to compensate for the vast difference in frame rates between film and broadcast/DVD. PAL frame rate is close enough to film to be able to do a simple speed adjustment without noticeable difference.

This is phase-shifting. Where the capital letter is the top field and the small letter is the bottom field, ordinarily the fields are lined up so:
Code:A B C D E F a b c d e f
Code:A B C D E F b c d e f g
However, occasionally duplicate frames are inserted at irregular intervals. -

I also encountered sources that are mainly progressive but use the by you described phase-shifting occasionally
only on fast moving scenes.
EDIT: Note that I'm reffering to the vdub telecide filter (by Donald Graft). -
