Which process takes place first? MPEG decoding or de-interlacing? I have an idea but I'm asking here anyways. I'm just wondering about how to come up with a way to ZOOM in on 4:3 widescreen material from LD, VHS (and to a lesser extent, non-anamoprhic DVD's). Do you take a 480p signal from a line doubler and use an HTPC to ZOOM in and squeeze the 4:3 widescreen? My DVD player right now is interlaced but I'll be getting an iScan for use with an AE100 or 200 projector.
