Hi Dr hanks
I think I need to explain something here.
When Faroudja started doing his deinterlacing thing, the sources were all "interlaced" material. As a result, there was sometime very significant movement between each and every field (as opposed to frame - there are two "fields" per "frame") which his software had to "make up", in effect.
As a result, deinterlacing material where the source was native interlaced, meant having to "make up" about half of the picture information that would be in the final "progressive" video output.
With the HD DVD players, the situation is entirely different. Since the source is progressive, the two "fields" have no movement between them, and the "frame" is carried whole and unaltered from it's original.
Therefore, "deinterlacing" 1080p24 material cariied as a 1080i60 stream should not really even be called "de-interlacing, technically. It would probably be more accurately termed "re-assembling".
My Vantage HD spits out absolutely line-for-line perfect 1080p from the Toshiba's video signal. If the process of re-assembling the source image is done properly, then there is no loss and nothin to fear.
Hope this helps..
