Rapid Fire Laser preset and interlaced footage

I'm having a bad interlacing problem when I use the Rapid Fire Laser preset (by Cogz). I have used this effect before, but I'm not sure if I ever used it with interlaced footage.
Has any once else experienced this particular problem with this preset? Can this preset be used in interlaced mode?

Any preset can be used on interlaced or progressive footage. Its more likely that the problem you are having is related to the rendered interlaced footage displaying as interlaced on your progressive monitor, resulting in a combing effect. If this is the case, its actually not a problem at all. Its just the result of trying to view interlaced footage on a progressive monitor. For television viewing, you will want to leave it that way, and for computer/internet viewing, you will want to de-interlace at the final export of the project.
Without a more detailed description of the problem, or better yet, being able to see it, this is really just a guess though, as its pretty much impossible to offer a definite diagnosis based on what info you have given.

I thought it was exactly what you said, but when I burned it to a DVD and watched on a TV it looked the same.
I am using interlaced footage of a model spaceship shot against a greenscreen. That part looks great on the computer moniter and on the TV. The problem is with the Rapid Fire Laser preset. It has a serious combing problem on both the computer moniter and on the TV. but the combing ONLY effects the lasers, not the interlaced ship footage, or the images I'm using for a starfield in the background. The lasers only look right within Fxhome, but Sony Vegas, Windows media, and on the (interlaced) TV the lasers have that "venetian blind" look.

I just did a test.
I redid the same video, except this time I imported the raw interlaced footage as Progressive, and when I rendered the Rapid Fire Lasers look fine (both on comp & TV).
Of course the problem is the actual video is interlaced, but since the ship isnt moving very fast the combing doesnt seem to be to big a prob on this particular video.
But it seems that the Rapid Fire Laser preset does not work on interlaced exports.

It seems like it would have to be something in the way you have the project set up, as that type of result could only happen (as far as I know), from the effect only being applied to one field per frame of the interlaced footage. Did you set up the project or set the imported footage to de-interlace?

Originally, I created the project as interlaced and imported the interlaced footage I did of the model ship. Then I did my greenscreening and added my background. Everything looked good up to that point. Then I added the Rapid Fire Laser effect/preset in and it (the lasers not the ship) looked all interlaced (except within Fxhome).
So I created a new project that was Progressive. I imported the Interlaced ship footage and did everything again, and the lasers look great, but I'm running interlaced video as progressive -- in this case its not a big prob, because the ship doesnt move to much/fast.
Is it something that I'm doing wrong, or does that preset just not work with interlaced footage?

btw, I rendered as uncompressed in all cases.
