Interlace lines on progressive footage

My DVD looks good on my computer, but lots of jagged edges on every interlaced T.V. I've played it on.

On page 51 of The HVX Book "Interlace lines on progressive footage" Barry talks about this problem.

Is there a way around it ? A pulldown? or do I have to film in "i" instead of "progressive" if I want to output a NTSC DVD for a interlaced T.V.?

What was HVX Bootcamp filmed in? (was it on a HVX?)
If I film in 720/24 pn or 720/30pn , editing in Premiere, How can I make my DVD look as good on an interlaced T.V.?

Any help would be greatly appreciated, thanks for your time!.....Dave
 
Just as a follow up in case someone searching the forum has the same problem as me, there is a solution:

My problem wasn't playing my 720/30p progressive dvd on my computer (progressive monitor) that looked good. It was trying to make it look good (or anywhere near that) on an interlaced T.V.
I needed 60i from my 30p footage
(Interlaced for interlaced monitor, progressive (or de-interlaced) for a progressive monitor)
Here is a tutorial on how to do that in A.E.:
http://library.creativecow.net/articles/solorio_marco/interlacing_progressive_footage.php
It basically involves doubling the frame count using pixel interpolation, rendering, then doubling the frame count (now 60p) And then exporting a 60i file (to make an mpeg2 out of).
While still not quite there, it's 100% better than anything I've tried so far. Pictures way sharper, most (not all) of the jagged edges are gone.
If some one knows a better method to interlace footage I would appreciate hearing.
thanks...............dave
 
Personally, I think these issues will continue to exist until folks wake up to the idea that with an HDTV, you really should be using only HD sources.

And that means Blu-ray in this case.

The flip side of that is why are you shooting in HD if all you have is SD playback? Just shoot SD and the problem won't exist.
 
There was a time when you had a class1 monitor as reference and if it looks good there it was allright on everybodys TV set.

Now you have CTRs, TFTs, Plasmas and whatnot. You can make it look good one but not on all.

The most insane thing is that we all produce interlaced HD (at least the networks in Europe require that) and the only screens/TVs poeple can watch HD on are not able to show interlaced.

Deinterlacing - whatever chip or algorythmus is used - means resolution loss up to 50%.
So in the worst case (750p) you end up viewing less than SD resolution on your full HD plasma. But the average guy would still have nothing but praise for his new plasma.

And what.... de-interlace? Who said all I had was SD playback?
Your missing the point, it's about already having the footage and somebody wanting a DVD and trying to make it work for them. (not a lot of people are asking for Blu-Ray)
