Widescreen DVD authoring and widescreen TVs Interlace issues

[burdell1]

I recently bought a 50" Hitachi LCD projection widescreen television. However, on the DVDs that I have made (which are usually things I recorded on Tivo and capture to the computer), there is a lot of interlace that is very visible. What is the best way to de-interlace the video? Is there any way to de-interlace the menus? Or anyway to make the video look better (since regular TV look like crap)?

so no one has had this problem?

I am not sure I know the reason for this but I have encoutered similar issues. I had been recording programs off TV using a TV capture card and then encode to MPEG2 before authoring and burning to DVD. They played okay on the computer but when played on my progressive scan DVD output to a LCD projector that is progressive scan capable, I could see interlace lines as you noted. Those same lines were also noticeable on regular TV playback also but not as bad.

In the end what I do is run the AVI file I capture through virtualdub, remove ads, resize to get over some overscan issues and pass it through a smart de-interlace filter before framserving to Mainconcept for MPEG2 encoding. Now the interlace lines are gone

I presume Tivo captures in MPEG2 format natively and probably doesn't de-interlace the picture. If you are able to get hold of the file that Tivo creates perhaps you could try de-interlacing the picture using Virtualdub or MC or TMPGENC before authoring to DVD

what do you do for the menus? are you able to de-interlace those as well?

I produce my own menus - well I just use the default menus that DVDMF provides. I have never seen any interlace problems with menus but then the menus that DVDMF produces are pretty static except for some motion in the small box that previews the video file you can select
