Just for amusement, I tried this procedure. First, I set up and
mofidied the script slightly, made sure the appropriate packages were
installed, then ran it. I set up a basic dvd.xml file, created the DVD
files, and burned the DVD. It worked - mostly. What was interesting is
that while the DVD seems to have copied, the aspect ratio was off.
While the original disk was in 16:9, the copy plays in full-screen.
Clearly I've missed something here, since the dvdauthor output clearly
stated it was in 16:9 format. Any thoughts? I'd hate to screw up my
home movies, etc, when doing this.
Thanks in advance,
-Don
