Mike - thanks for the reply. Here's a status update.
Problem 2: Changing "Mixer device" to "ALSA:default" did fix the mute
failure on both frontend systems, as you suggested.
Problem 3: The MythWeb preview image problem turned out to be a php
configuration issue. In the course of upgrading Apache and php, the
option to allow fopen for URL's was turned off and I missed it. On
Gentoo with Apache 2.2 and php 5.3, I had to change
/etc/php/apache2-php5.3/php.ini to have:
allow_url_fopen = On
This allowed the preview images to be generated and display properly on
the MythWeb recorded page. (The names changed from *.mpg.100x75.png to
*.mpg.-1.100x75.png, but that seems irrelevant.)
I'm still looking for a solution to Problem 1: "Error: GetPlaybackURL:
...", although this doesn't seem to be causing obvious problems.
