Video has strobe like problem

This is nearly killing me. I video tape local stock car races and then sell the DVD's at the track. In the past I had no issues, but a couple weeks ago something seems to have changed and its killing me.

What happens is on some of the video you get this weird strobe effect on some of the background/foreground objects as the camera pans by. Here is the weird thing.. it seems to happen only after DVDA gets hold of it. Here is what I mean.

Video on the camera.. looks great on cam.
Video on camera connected to TV directly... looks great
Video captured as an .avi file , play the file..... looks great.
Did some edits in VMS saved as an .avi file which was about 20gb, import file to DVDA and Prepare/Burn.... DVD sucks, picture all strobelike especially on the bright daytime shots.
Ok, skip the VMS, put half the video straight into DVDA, file is 9gb or so, Prepare/Burn... DVD comes out strobed and junky. I really will give you headaches to try and watch it.

I don't understand why its doing this and the only thing I can figure out is its something to do with the fast motion but I can't understand why it hasn't effected earlier DVDs of races, unless it was something to do with the brightness factor.

I have made a bunch of coasters and they take quite a while to render then burn so I really gotta figure this out as I need to replace all the videos I sold with quality ones.

Did you have Reduce Interlace Flicker turned On or Off?

Which version of DVDA Studio (3, 4, or other)?

Version 3. build 93 Not sure on the interlace flicker, I can check when I get home. Where would I find that setting?

For the media in question, on the right side under "Menu Page Properties", hit the GENERAL button.

btw, are all other things still equal (same camcorder, computer, OS, no new software, etc...)?

Does it matter then I am not making a menu based movie but just as single movie?

Ok the problem has a name! I guess its called Vertical Filtering? http://www.hometheaterhifi.com/volume_7_4/dvd-benchmark-part-5-progressive-10-2000.html there is a section describing it perfectly in there...... unfortunetly, nothing there to say how to overcome this or fix it.

It is driving me nuts cuz I tape each week at this same track and its just this ONE darn video that won't come out.
