when i create a DVD in VideoWave (Rox ver.9) and I load pictures (*.jpeg files) and video clips *.avi files)...

When I make changes, ie. duration of frame, move frame, add picture or video clip in VideoWave on a random basis the next frame may come up blank, the VideoWave viewscreen of the file will be black, however if i have added text it will be on the black viewscreen ... it may run through 1-3 frames and them next VideoWave viewscreen is normal (visable) ...

I can force the picture (file) to load via double clicking the picture, which takes it to PREVIEW: ...It is then visable in the VideoWave viewscreen ... can't find a consistency (file size) (lenght of frame) (transition duration)...

Going to INTERNAL TRACKS does nothing for me ...

What command am I overlooking...

I can't follow at all what you are doing I don't even know what you are trying to do
Please explain a bit more clear, step-by-step what your are trying to do and what you are doing.
At the moment all you have given is a lot of jumbled phrases that don't mean anything.
