Gents, many, many thanks for all your help. But I decided it was
hopeless, threw in the towel, and started over from scratch. Using your
advice on static ip, hostnaming, etc., I am happy to report I now have
a working setup. However, although I can record and play, I am getting
some messages in the frontend log that indicate problems. To wit:

The first three lines are repeated lots of times, maybe 20 or so. I found one post the related this error to ffmplayer playing a blu-ray disk, but this is a broadcast recording. Any ideas what the problem could be here?
Also there seem to be some issues with ALSA. Sound is working after I removed alsa-plugins-pulseaudio per instructions on the wiki, but as you can see it doesn't like and can't modify the audio buffer size. I am using the audio defaults (i.e. ALSA:default) on the frontend. Should I do what it says and increase the buffer with tee /proc/asound/card0/pcm0p/sub0/prealloc (not sure what tee is)? If so should the buffer size be 6016?
Many thanks...
Steve
