In DVDx , any smart people there what these settings are for

[silab]

Their site is down and I couldnt find any information about the settings below. I dont know what to select among them whenever I rip. Anybody can explain?

Export Settings Panel

ZOOM
None (letterbox 4/3)
Medium (4/3)
Pan Scan (4/3)
Full (16/9 or 4/3 input)
Custom

Resize Filter
Nearest neighbourhoud
Bilinear
MMX Bilinear
Bicubic
SSE Bicubic
Pseudo Bicubic
P4 Bilinear

[Twin]

I'm pretty new to this , but my guess is:
None (letterbox 4/3)
Medium (4/3)
Pan Scan (4/3)
Full (16/9 or 4/3 input)
Custom

are the view, different settings depending on what format the movie is, and how you would like to view it. Let's say: Widescreen -> Normal TV.
(Just a guess)

The resizefilters, hmm, haven't really figured that out yet, but hmm, maybe how the picture is drawn?

I'd be loved to be corrected here, since I wanna know too.
