| Post subject: | Black screen when trying to watch tv |
K6-500 Hauppauge PVR-350 Got installed, able to do mythfilldatabase. Video device set to /dev/video0 When I try to watch TV, I get a black screen. I have to kill mythfrontend and in xterm I see: Enabled verbose msgs : important general mythtv: could not connect to socket mythtv: connection refused Failed to create lirc socket for mythtv Unable to open mixer: '/dev/mixer' I do not have a sound card installed because, once setup, I plan to only have the TV connected to the myth box. Is a sound card necessary with the PVR-350? If so, I have an old ISA Sound Blaster compatable sound card (has ESS AudioDrive chip)...will this one work? Also how can I be sure that I have correcly selected /dev/video0 as the capture card? Any help is appreciated. Thanks, Jason |

Sounds like your mythtv frontend can not communicate with your mythtv backend. Run mythtv-setup and check that you have entered the correct IP address. |

Would that be the "Master Server IP adress"? I do have that correctly set to 10.0.0.101 which is the IP address of the computer. I have the backend and frontend running on the same machine. |

If you have the backend and frontend running on the same machine then you can just leave all the default addresses. |

Also, when I go to the first console (Alt-F1) I see a line that states: Starting MythTV server: mythbackendQSettings: error creating /.qt I seem to be able to record TV and when I go to view the recording I see the recorded program in the lower right corner, but if I try to view the program full-screen I get a black screen and mythfrontend locks up. Thanks again, Jason |

You can ignore any errors about .qt. Since the back/frontend are on the same machine you can(should) leave it the IP as 127.0.0.1 . What chipset on the motherboard? Have you check the ivtv archive? |
