Bug marked as duplicate of this one has a suggestion:
I managed to get both cards working by playing with the /etc/init/mythtv-backend.conf file. added "and started mysql and started udev-finish" to the dependencies start on (local-filesystems and net-device-up IFACE=lo and started mysql and started udev-finish) -- myth-backend started before kernel driver it needs https://bugs.launchpad.net/bugs/556204 You received this bug notification because you are a member of Mythbuntu Bug Team, which is subscribed to Mythbuntu. Status in Mythbuntu, Ubuntu derivative focused upon MythTV: Triaged Bug description: In Lucid there isn't a dependency for myth-backend on kernel modules being loaded. The result is that it can run before the kernel module for the hardware is finished loading.

Perhaps you should re-read the installation instructions? 2010-04-05 22:06:05.817 mythbackend: No capture cards are defined: Please run the setup program. My current hack, which fixes the problem but is totally the wrong thing to do, is to add the following line to /etc/init/mythtv-backend.conf /bin/sleep 60 Instead a proper dependency needs to be added in there, I just don't know enough about upstart to know how to do it. _______________________________________________ Mailing list: https://launchpad.net/~mythbuntu-bugs Post to : mythbuntu-bugs@lists.launchpad.net Unsubscribe : https://launchpad.net/~mythbuntu-bugs More help : https://help.launchpad.net/ListHelp
