Completed DVD Slideshow Cuts portions out

Hi...I do my DVD Slideshows using Roxio VidoWave8. I have no trouble with slideshows containing about 50 photos, but when I did one with 214 images, I can watch it fine on the TV (DVD players)... for about the first 14 minutes or so, THEN it goes straight to the last 2 minutes or so of the slideshow, where shows all photos from there on and ends where as it's supposed to.

When I render, then preview the finished product before burning, everything is there audio and video wise.

By reading prior posts, I thought maybe there was a limit as to how many photos I can use, but I couldn't find anyting in Roxio Help that tells me how to change the number of pictures allowed if that is the case.

The Production Duration is 29:37, and the Audio duration is 29:38.

At one point I thought maybe it was the audio I was using, but the first time I did the shorter slideshow it contained the middle portion that was dropped from the longer one I later completed....so now I'm thoroughly frustrated.

This is what I get at the end of the burning....It says "Overall Progress 100%" Current Task Completed 100%" Then a box comes up that says "Access to the specified device, path, or file is denied" What does this mean?
Thank You....
