Thank you, yes this certainly helps. From bits I've seen here and there,
I'd begun to suspect the audio component was the issue. I'm a rank novice,
and had probably accepted a default in Nero Vision Express when I captured
those files (from my Sony camcorder). No particular rationale behind it.
I just want to make movies and slide shows from family DV tapes and jpegs,
and eventually convert old family VHS archives to DVD. But I encountered
trouble in Nero burning those files to DVD ( - I did manage to make SVCDs
from them - ), which is why I started researching a dedicated editing
package and ended up with Studio.
Yes, I still have the tapes, and I guess I will recapture into Studio. But
first I want to do some reading. I understand what a codec is and that
there are all these formats floating around, but I need to learn more about
the distinctions between them.
So far, I've yet to find as cogent a perspective in the Studio help file as
you just provided in a few short paragraphs. Thanks again! -Ron
