Mythbackend problem after update

I am facing the following problem after updating mythtv.

The installed packages are:

sip03ds ~ $ sudo yaourt -Ss mythtv | grep installed
extra/mythmusic 0.21-3 [installed] (mythtv-extras)
extra/mythtv 0.22-3 [installed] (pvr)
extra/mythvideo 0.21-2 [installed] (mythtv-extras)
extra/nuvexport 20090413-1 [installed]

after updating mythtv the backend refuses to start. Even though is displays that it is starting normally:

sip03ds ~ $ sudo /etc/rc.d/mythbackend start
:: Starting MythTV Backend                                                                                             [DONE]
sip03ds ~ $

for some reason it shows that the backend is unavailable.

sip03ds ~ $ mythfrontend

Re: Mythbackend problem after update

As I found out here http://bbs.archlinux.org/viewtopic.php?id=85090 you need to uninstall all your plugins.

You also need to run mythtv-setup first (without the backend running) for it to upgrade your database

You can re-build all your plugins through ABS to get them working again.

Re: Mythbackend problem after update

The problem is that I am using mythtv as a DLNA server in order to broadcast music and video to TV sets and not for TV viewing / recording, the point of using mythtv is using the pluging abilities it gives :-(

Re: Mythbackend problem after update

I removed all the plugins and reinstalled mythtv. Configured it as advised on the wiki (without dropping the database schema) but the server is still not starting up correctly.

I found out that the server is starting and and stopping when I run:

sudo /etc/rc.d/mythbackend start

when I start the front end, the front end cannot connect to the back end because it is unavailable.

in case I start the server manually:

sudo mythbackend

I am able to connect via mythfrontend and mythtv is working correctly. Any suggestions to change the daemon script ?
