1080i to 720p

What's the best way to resize and deinterlace a 1080i source to 720p? Everything I try ends up looking bad.

TFM() + TDecimate() has yet to let me down

as for resizing, spline36resize() or lanczos4resize() are my weapons of choice

and just to be sure...you should do deinterlacing/IVTC BEFORE resizing

If this is 1080i H.264, then I think there might be more streamlined methods to deal with MBAFF and PAFF automatically, but I haven't looked at either of those closely (since I've never had to). If it's MPEG-2, see Kariudo's post. And yes, always always always deinterlace/IVTC before resizing.

TFM(mode=1,pp=5,slow=2,micmatching=2,clip2=tdeint(mode=2,type=3)).TDecimate()
Spline36Resize(1280,720)

If you're dealing with an MPEG2-TS transport stream then you want to crop it before the resize but after IVTC, same for an MPEG4-AVC transport stream. If it's from a bluray you shouldn't need any cropping but that isn't always the case.
