| Post subject: | Watch TV with BT878 not working getting static with green |
Wondering if someone out there can help me. I've got a Zoltrix Genie TV Tuner (BT878 based chipset) and I've only been getting a green screen with static/snow on top when I launch Watch TV. I've carefully followed the "mythtv-setup" instructions, and to the best of my knowledge, I've set it up correctly. I believe that my bttv options should be card=46 and tuner=21, so I've edited the bttv file. And yes, I know the cable from the wall is working. |

when you boot, does "dmesg | grep bttv" show that it is using your card and tuner options? Can you get a picture with xawtv. That should be the first step, and then you need to start looking at the way you have your channels setup in the myth database. |

Hi there, The following is the "dmesg | grep bttv" mythtv@Cypress:~$ dmesg | grep bttv bttv: driver version 0.9.16 loaded bttv: using 8 buffers with 2080k (520 pages) each for capture bttv: Bt8xx card found (0). bttv: Bt878 (rev 17) at 0000:00:09.0, irq: 10, latency: 32, mmio: 0xd8000000 bttv: detected: Zoltrix Genie TV [card=46], PCI subsystem is 15b0:4000 bttv: using: Zoltrix Genie TV/FM [card=46,autodetected] bttv: gpio: en=00000000, out=00000000, in=00fcffff [init] bttv: using tuner=21 bttv: i2c: checking for TDA9875 @ 0xb0... <6>ts: Compaq touchscreen protocol output bttv: i2c: checking for TDA7432 @ 0x8a... not found bttv: i2c: checking for TDA9887 @ 0x86... not found bttv: registered device video0 bttv: registered device vbi0 bttv: PLL: 28636363 => 35468950 .. ok bttv: PLL can sleep, using XTAL (28636363) bttv: PLL: 28636363 => 35468950 .. ok and xawtv does not work, either. I do not get a picture, only static/snow. The channels were downloaded by XMLTV listings grabber and appear in the channel editor. I'm stumped. Thank you for your help so far. |

Where do you live? Have you selected the right frequency table in xawtv and gone through all of the channels? If you can't get xawtv to work then I would question whether you have the right card/tuner options. |

I live in Canada so I selected the frequency table for "us-cable". It may well be that the card/tuner options are incorrect. Just to confirm, should I be adding the line "options bttv card=46 tuner=21" to the "/etc/mythtv/modules/bttv" file? Am I missing something? |

us-cable-hrc is the other possibility. Check with your cable provider. |

I had tried "us-cable-hrc" as well, but it didn't work. |
