<p class="MsoNormal">I’ve got a Debian 6 box running mythtv 24.1 installed via the debian-multimedia repo. It has a PVR-150 installed and is running as a SBE. I have run mythtv-setup and configured the capture card, sources, connections, etc. The problem is
when I run the daemon using the mythtv user created during installation, the backend complains that there are no captured cards available--like this:<o:p></o:p></p>
