[mythtv-users] bizarre database corruption

[Greg Woods]

At least, I am assuming I am seeing database corruption. I have the same
problem on a mostly-working Fedora 10 system, and a brand new fresh
install on Fedora 13 (same machine and therefore same hardware, dual
booting while I get the new one working).

The basic problem is that I cannot get my HDHomerun tuners working. The
two HD-PVR tuners work fine. The problems I am getting look like it has
to be bad data in the database somehow.

First, if I go into mythtv-setup and add the HDHomerun tuners, it looks
OK at first, but if I then examine the capture card table, each tuner is
in there twice with two different cardid's. They only show up once in
mythtv-setup. And, they don't work. I scan for channels on the antenna
tuner and it doesn't find any. I also can't tune any channels on the QAM
tuner. (The HDHomerun tuners work fine with the Silicon Dust software on
Windows, and even if the HDHomerun had broken somehow, it wouldn't
explain the double entries in the capturecard table).

To fix this, I first tried to do a partial restore with
mythconverg_restore.pl . That appears to work, but then as soon as I
fire up mythtv-setup after that, it wants to upgrade from (blank) to
1264, and of course it doesn't work. If I do a full restore, the same
old problems return (presumably because I have restored the same old bad
data). This all happens identically on the production Fedora 10 OS, and
also on the brand new F13 OS.

Is there anything I can do to fix this that won't cause me to lose all
my recordings? I'll be happy to provide any other info that is needed.

Thank you,
