Post subject:  No video or sound
I am trying to configure KnoppMyth R5D1 on this new hardware and I am not having any luck getting video or sound. I am not sure what to look for. Thanks for your help

Well, you're off to a good start having provided the right log extracts. The IVTV setup all looks healthy, so I'd have to geuss that you've got some kind of setup issue. Go through the checklist on this troubleshooting page, paying particular attention to conofigurations settings like "wrong frequency set" and such. http://www.knoppmythwiki.org/index.php?page=BlackScreenWatchingTV

OBTW - It probably wouldn't hurt to upgrade to the latest ivtv driver for that kernel which would be 0.7.3, the CompileIvtv instructions on the wiki may look complicated, but they're actually just a matter of singing along by following the bouncing ball. For R5D1 it should take all of about 5 minutes. http://www.knoppmythwiki.org/index.php?page=CompileIvtv

Thanks for your reply. I upgraded ivtv to 0.7.3 but still don't see anything.

I think ivtv is working. I can do 'cat /dev/video0 > /tmp/1.mpg' and play the file well with mplayer.

In the logfile /var/log/mythtv/mythtvbackend.log, I see the following
2006-12-17 14:57:55.097 adding: mediabox as a client (events: 1)

Where is this 'TV Settings' option?

Thanks a lot

I think it's refering to the mythtv-setup utility I was suggesting that you rerun. You did pick MPEG-2 for the card type right? In any case go back through that. Under 1. General make sure that you got the right transmission format (for North America - NTSC-M) and the appropriate Frequency Set (about the 3rd page in) you may need to try the various options. Under 2. Capture Cards you need to tell it that /dev/vide0 is an MPEG-2 Encoder. Under 3. Video Source you need to set up your channel lineups (in N.A. this is zap2it, and you need to create an account there first) Under 4. Input Connections you need to associate your channel lineup from 3 with your capture card input from 2.

Thanks a lot for your help. I got it working!!!

I had set the tuner card to V4L device rather than the PVR-X50 option. It started working flawlessly after this!

Thanks again
