before I get to your questions Andrew, I have to report a partial success.
I went back up this thread to see if I had missed anything, and I
found and decided to try inserting the symlink name, exiting BEsetup
and then re-entering. first off, of the three cards, only two are
currently productive, a digital and an analog, so after entering the
symlink names for these two cards, exiting and going back in, when I
selected the digital symlink capture card it presented the
/dev/dvb/adapter0/frontend0, but when I selected the analog symlink
the symlink name stuck and opened, much joy, so I went into "input
connections" and configured both and went back to "capture cards" and
deleted the digital symlink card, exited and the FE is happy with
that, me too!

So Andrew, after considering the info above, I think permissions etc
are OK, and as far as I know I'm making changes as "mythtv" not
positive though, if memory serves me correctly setting up this box I
used the same password for root and all else, my bad in retrospect.
 I'm leaning toward having to fix the digital cards pointing to "net0"
and "demux0" as being the path to full joy. can anyone corroborate and
or direct?  Again much thanks to all!   Daryl
