| Post subject: | PVR-250 Black Screen Fix |
I believe I have the begining of a solution for folks with PVR-250s who still do not get a picture after having tried all of the things in the following thread: PVR-250 TV Tuner Not Working After reading the following FAQ at the IvyTV site, I figured out how to get a picture on my new PVR-250. http://ivtv.writeme.ch/tiki-view_faq.php?faqId=1#q13 I must change the input the driver uses from 0 to 4. The following command does this: /usr/local/lib/ivtv/utils/test_ioctl -p 4 The problem I have is that even though I modify the /etc/sysconfig/ivtv/cfg-0 file to reflect this not-default input, the /etc/init.d/set_ivtv_params script calls the driver with input 0. What do I have to change/do to get the system to use input 4? TIA |

Do you by any chance have Code: #IVTV_TUNER='4' or Code: IVTV_TUNER='4'
in /etc/mythtv/modules/ivtv/cfg-0? By default it's commented out. It may be a bit obvious, but just checking... |

Obvious, but still a good question. Yes, I uncommented it. In fact if I run it at any time after boot by typing /etc/init.d/set_ivtv_params start it sets the correct input (4) and I can then select "Watch TV" from the Mythtv interface and I get picture and audio (although fairly choppy - I'm not troubleshooting that yet!). |

After boot up a dmesg gives me this: saa7115[0]: decoder set input (0) After I run /etc/init.d/set_ivtv_params start I get this: saa7115[0]: decoder set input (4) Is there a way to do this when the module loads? Maybe options ivtv input=4 or something along those lines in /etc/mythtv/modules/ivtv? |

This is fixed. I had not selected which input to map to which device. This is done in mythtv-setup in the Input Connections screen. Oops... |
