| Post subject: | Blank screen when selecting Watch TV |
With the help of several messages here I (a noob to Linux and MythTV) got KnoppMyth installed and the internet portions working (XMLTV, Weather, News) but when I select to Watch TV, I get a total blank screen. I've tried a couple of different NVidia video boards (MX400 and an older TNT something I think) while using a ATI TV Wonder VE. Right now I'm using my computer monitor until I get a different video card with TV Out. How do I determine if the TV tuner card is even working? I see it is recognized on bootup by MythTV as a BT878. I've gone through the NVidia driver update but that caused the screen to go blank on bootup without ever getting to the MythTV screen. Do I have to change the tuner type or is there some other settings I need to change?? I'm at a loss as to what to even look for next so any help would be greatly appreciated. I'm sure someone here has some ideas for me to check. Thanks. Steve |

http://mythtv.org/docs/mythtv-HOWTO-20.html#ss20.30 You can exit MythTV, start and xterm and run xawtv to determine if the tuner is working... |

Thanks for the quick response. I ran xawtv the I'm seeing TV in black and white. Output to xterm from launching xawtv shows: This is xawtv-3.88, running on Linux/i686 (2.4.21-xfs) Warning: Cannot convert string "-*-ledfixed-medium-r-*--39-*-*-*-c-*-*-*" to type FontStruct Xlib: extension "XFree86-DRI" missing on display ":0.0". v4l: timeout (got SIGALRM), hardware/driver problems? ioctl: VIDIOCSYNC(int=0): Interruppted system call ioctl: VIDIOCMCAPTURE(frame=0;height=32;width=48;format=4): Device or resource busy ioctl: VIDIOCMCAPTURE(frame=0;height=32;width=48;format=5): Device or resource busy ioctl: VIDIOCMCAPTURE(frame=0;height=32;width=48;format=1): Device or resource busy ioctl: VIDIOCMCAPTURE(frame=0;height=32;width=48;format=7): Device or resource busy ioctl: VIDIOCMCAPTURE(frame=0;height=32;width=48;format=13): Device or resource busy ioctl: VIDIOCMCAPTURE(frame=0;height=32;width=48;format=15): Device or resource busy no way to get: 128x96 16 bit TrueColor (LE) I guess that says something about why it's b/w?? I currently have the older TNT video card installed. I think it has 16MB or ram. I assume that should be enough for TrueColor at this resolution?? But I can put the MX400 (64MB) back in if that helps. Sorry for the newbie 'walk-thru my problem' request, but do you have any ideas on what to try next? Thanks so much. Steve |

I would be looking at the tvcard setup. make sure that the bttv driver is using the proper card# I think there are some posts on the forum about the ati tvwonder and what the option line should be. |
