Thank you for the reply Bolek;
First, there is a discrepancy between the mythtv 20 release notes and the mythtranscode help file
Also, you are correct, paremeter  is "-e dvd" NOT "--dvd".  Mythtranscode also does not produce an error  when "--dvd" is used.

Next, thank you for the two dvdauthor commands - that was what I needed.

Lastly, this in not a mythtv problem, but I'll mention it anyway.
The sequence of the options specified for "growisofs" is critical when burning a DVD-RW! 
(as opposed to a DVD-R)

[growisofs -dvd-video -Z /dev/sr0 -V 'The Saint' /mythworkfile/TMPDIR]   DID NOT WORK; 
The dvd-rw this command produced would not play on the stand-alone dvd player

[growisofs -Z /dev/sr0 -dvd-video -V 'The Saint' /mythworkfile/TMPDIR]   The DVD-RW this command 
produced played without any problems on a stand-alone dvd player.
