I am going to spend a little time, following your ( very welcome ) outline
to find what it is that changed on the old system.

I was able to go around the problem by booting up under a older Fedora 14
live disk.
All of my recordings copied to the USB portable hard drive with no problems.

I am a little bit eager to upgrade this system thou, as I want to 
explore the
Android connection to mythtv.
I would like to find something like mythweb that will run off of my 
tablet(s)
and/or phone(s) ( this may already exist ).


One of my phones, has a HDMI port so that might get interesting also.


Thanks again,
   Bert
