Some new information.  I did a recording with mythfrontend off and it had
glitches.  So that didn't work.

I also think I might have figured out why my beloved Mythbuntu 8 was not
working. I said that it died because of a disk failure but what I didn't
say was that it was the second disk, one that was just for additional
storage. What occured to me today was that I probably needed to just delete
the reference to that now missing storage.  I ran mythbackend setup as part
of documenting the settings and noticed that the second storage location
was not there and then I saved the settings.  I am thinking that might fix
my Mythbuntu 8 system. Then I can chalk up the multitude of hours I spent
trying to get Mythbuntu 16 to work to "entertainment".

Just for a point of comparison to document the "progress" that myth as made
in the last 10 years. I reinstalled the 6200 video card and the old HD and
there is no ripping like there was with Mythbuntu 16 with that card and no
glitches.  I am, as I have said, perfectly happy with the performance of
Mythbuntu 8 so if this proves to actually be stable, I may just quit here.
I am recording and watching at the same time in "top" below and there is no
swap used.  I notice that the buffers space is much smaller and I may have
increased the buffers on the new setup at some point in the debugging stage
but in any event it is of interest.

But I have a 1T HD coming today so I have to decide which OS I am going to
put on it...
