DVD Architecture - rendered video blackens out parts

[TPtopcat]

Hi. I am using DVD Architecture Studio Version 5 and I am rendering (preparing the project to a specified folder) so that I can then burn it to a DVD. The whole thing looks just fine when I preview it in the DVD Architecture application, but once it is prepared and rendered, sections of it have missing video so that all you get is the audio with a black screen, then other sections have even lost the audio parts. Any suggestions as to what is wrong?
Thanks!

DVD Architecture? Never heard of it. Do you mean "DVD Architect"?

No idea what's going wrong. Maybe you could give a little information about your source videos?

Thanks for responding! Yes! Sorry.. I meant DVD Architect. What info can I provide on the source videos? They were all created using Sony Vegas Studio and they are all AVCHD format. I have lots of other projects using the same file format using DVD Architect and they were fine but this one just seems to randomly black out whole sections of a video, or in some cases it just has black out "flashes" throughout the video... each time I render it, they are in different places so it never blacks out the same way...

Once you render in Vegas Movie Studio you shouldn't have to render it again in DVD Architect. Just create your menu and burn the DVD with DVD Architect. Or use ImgBurn. Vegas Movie Studio will also render to your hard disk. I use the MP4 setting.

I have never rendered in Vegas before... never had to... that is what I find very strange though. Why is this happening now after years of doing it the same way and having no (or little) problems...

If I render it in Vegas, can I still bring the rendered versions into DVD Architect and create my DVD the way I want it there for burning it to DVD? I use DVD architect to make it "pretty" with menus and music and a scene selection menus, etc.
