[mythtv-users] Encoders disappeared

[Bob Gamble]

Of course, things were running like a top using Ubuntu 7.10's (gutsy) mythtv
setup.  I decided to put the soon to be released 8.04 on another machine.
That would have been fine on its own, but wanted to see how mythtv might be
different.  I think the mistake I made was installing the mythtv-backend
package and going to configure it.  Though I didn't have a tuner card in the
computer with 8.04 on it, I wanted to look at any options that might have
changed so I could start researching them.

In the General section of the mythtv-setup screen, I noticed it
automatically picked up the master backend server's ip address, database
name and password.  I stepped through all the configurations and from what I
recall, only chose to not query mythfilldatabase automatically.  I didn't
think running this on a different machine without a tuner card would have
any affect.  After backing out of mythtv-setup, I started the mythfrontend
on the newly configured machine (Ubuntu 8.04) and pointed it at the backend
server.  It brought me to the main screen where I chose Media Library->Watch
Recordings.  The error message popped up that I was using version .40 on the
computer whereas the master backend is version .31.  I've seen this error
before and sort of expected it.  But I had to try.

Now for the problem :)  For whatever reason, I lost the encoders on the
master backend and a secondary backend I have had running smoothly for
almost a year.  Both cards are Hauppauge; a pvr350 on the master and pvr250
on the secondary.  The are still recognized at boot as I can run lspci and
see:

Master backend
01:06.0 Multimedia video controller: Internext Compression Inc iTVC15 MPEG-2
Encoder (rev 01)

Secondary master
02:00.0 Multimedia video controller: Internext Compression Inc iTVC15 MPEG-2
Encoder (rev 01)

I also ran dmesg|grep ivtv and got:

I got similar output on both machines.  I tried re-adding them in
mythtv-setup under the Capture Cards section.  Even though they are
recognized as MPEG2 encoder cards and have the device /dev/video0 connected
via s-video, they no longer get added.

I've tried reconfiguring packages such as mythtv-backend, mythtv-database,
mythtv-common but none of those solutions work.  Before doing all the
troubleshooting, I uninstalled mythtv from the test machine and shut it down
so it wouldn't be interfering with my setup.

Does anyone have a clue what might have happened here?  I even reset a card
in one of the machines to see if that would have an affect but it was no
go.  I have a feeling the problem lies in the database, but I don't know
where to look.  I appreciate any tips you may have.  Thank you.
