First of all I would like to thank all the persons who take their time to help out my kind of ignorant persons, who are completely dependent on their mercy. Ignorance is not bliss.

This time Im facing a strange problem. Im having some progressive videos. When rendering to interlaced, same frame rate, then everything looks fine on computer screen, but on tv motion looks heavily waved, thick line shifts. Dont have a frame to show, its only appearing on a TV.

I tried to preview the source progressive material on TV and it looks fine.

So Im using Vegas and rendered same files before and had no problems. But this time Im having Dynamic RAM Preview off, cause I used PluginPac for importing VDub filters.

Could that cause the problem?

Thats all I can think of, but already burned few dvds with different setting to figure out the error and this time I would like to make it sure first.
