What a difference a day makes, this morning the card wouldn't open using
any of the three most recent kernels. Now I suspect something in my UDEV
rules, because going into BE setup shows the two ASTC cards, one
adapter0/frontend0 and the other with the unique name HP1250, so I deleted
all capture cards (not on host), then re-added them (using UDEV for two of
three cards) and all seems well again. Could my current woes then be
related to: using Gparted to clone an older, but fairly recent rsync'd copy
of my 14.04 lts with Myth 0.27 onto a new 32GiB SSD? My curiosity is
academic as the Game will record this afternoon and the wife's shows are
all queued up.
 Happy Canadian Thanksgiving to all!    Daryl
