Thanks for the response.  Here are the answers to your questions:

1.  I have let it sit there for 10 minutes and nothing happens, just 100%
cpu and a frozen screen.  I can get a hall of mirrors effect if I drag
the terminal box around on top of whats left of the frontend.  When my
system worked before I remember that it would pop up a progress bar on
the SCREEN that says what rom-system it's detecting for, but that doesn't
even happen (just the LCD information status changes to "scanning for
games...").
2.  I tried your good suggestion of a single rom in a directory, it still
fails, the same way.  Let it sit for 5 minutes, no change.
3.  I tried an empty directory as well, same result.
4.  The permissions are 644 for all files and 755 for the directory which
houses the files.  The mythfrontend process owner, is the owner and the
group property of all files and the directory.
5.  I have tried the "Clear Player Data" option several times, since I don't
have any to begin with.  It does nothing.
6.  I deleted my N64 gameplayer info (it was the only one), and created a
new "fake" one and tried scanning for roms in both an empty and single file
directory, results still the same.
7.  I ran a log of "mythfrontend -v all > log" but no errors came out at the
end of the file.  It's like it just goes off into la-la land chewing up cpu
cycles.  I let it run for a few minutes after choosing to scan for roms,
when I killed it the time was 20:38 so there were no entries once it froze
at 20:35.  The following is an excerpt from the log file of the last ~20
lines.

Any more ideas?  I can post a link to the entire log file if you think it
would be useful.
