Beyond frustrated!

I have done, I think, everything I can try in getting my film to look crisp on dvd. However, the motion in the film when viewing on a television seems to have all sorts of jaggies in it. What is causing this? I have set my project at Best, Lower Field First, None on De-interlace, and it just doesn't seem to work. My bit rate is set at an avarage of 8,000,000. The Camera I use is the Sony HDR-FX1. Does any have any suggestions? What are the best properties settings when one is putting on a dvd that is going to be shown on a big screen and on television? Please, any help would be greatly appreciated.
Also, when I play this off the dvd on a computer the film looks great! with no jaggies.

Firstly was this shot in HDV?
If so how did you down convert to SD?
During the donwconvert if doing it in Vegas one should specify a de-interlace method otherwise all manner of nasties can creep in.

Just to be clear about this, if you shot HDV, are editing on a HDV T/L and rendering directly to SD mpeg-2 then you are downconverting and should really specify a de-interlace method. Blend will give the highest resolution but possibly some jaggies on motion. Interpolate will give slightly lower res with no jaggies on motion.

Good points and while I'm just assuming it was shot in HD here, HDR-FX1 is an HD camcorder (1080i). One can record in SD with that camcorder as far as I know (I don't yet own one, but hope to soon).

Since 1080i is interlaced, then one would have to make sure there is consistency in format from capture to final render

Sorry, forgot to add that this was shot entirely in SD

OK, that cuts down on the number of variables!

So it was shot as DV, in that case it's lower field first, not that this matters as Vegas will convert the field order correctly regardless of project setting if you don't mess too much with the standard templates.
So what I think your problem is, is simple interlacing.
You've shot 60i, right?
You've encoded to mpeg-2 as 60i, right?
You're watching the final DVD on a device that's basically a progressive scan device that's not so hot at de-interlacing. A regular CRT TV should show your video just fine, some LCD devices and/or projectors not so well.
If I'm guessing right then you may need to de-interlace your footage youself and make what is a 30PsF DVD (assuming you're working in NTSC, if in PAL it'll be 25PsF). All this means is the display device is given two fields with no temporal separation so when it merges them they line up i.e. no jaggies.

Assuming you're still with me and I haven't gone totally nuts then there's a number of ways to do this. Best one I've found is Mike Crash's Smart De-Interlacer plugin for Vegas. Heaps of good info on using it on this forum. If you get stumped / can't find it let us know and someone will dig it out for you.

Try adding the "Sony Broadcast Colors" filter with the "Conservative" preset globally, or at least to a section you can burn to DVD and test on a TV.

Oh, and you should probably be using a 29.97 timeline and rendering to a standard 29.97 MPEG for the DVD.

I found Mike Crash's site but the link for the de-interlacer was not working. Any ideas?

They might have that on the VASST site.
