I'm now running a Hauppauge PVR-150 capture card in my MythBox, running KnoppMyth R5A26. MythTV recognizes the card, and can record/view footage from the card. Zap2It's channel line up downloads fine, and MythTV has no problem parsing the data.

However, MythTV refuses/does not/cannot/will not change the channel on the tuner. Even If I set the EPG to record on different channels, I still only get content from one channel.

I'm attempting to use the us-cable frequency table, on the NTSC standard. I'm using the default IVTV module, and here is the dmesg output:

Code:

Someone suggested that this might be due to an unrecognized tuner chip in the card, but someone else suggested it might be a problem with my driver. Any opinions or ideas?

Have you tried ptune-ui.pl to manually change channels? This would allow you to take mythtv out of the equation and directly interact with the card.

The process is either:
a) get mythtv to play a channel (any channel), or use mplayer to play /dev/video0.
b) fire up ptune-ui.pl. Its a GUI app

Then mess with the settings - frequencies, region etc. You should be able to change channels.

If it works here, you can copy the settings back to mythtv-setup.

Cheers.
Paul.

When you don't want to use a GUI you can use ivtv-tune (e.g. ivtv-tune -tus-cable c1).

Maybe you should upgrade the firmware: http://ivtvdriver.org/index.php/Firmware_versions
You can use ivtvfwextract.pl to extract the firmware (make a backup of /lib/modules/*.bin before!).

Also check your harddisk for errors (if it's /dev/hda). This should have nothing to do with that problem, but when your hdd is defective you won't have fun in future

--> no good sign!

Hey - did you ever get this working, and if so - how'd you do it?

I'm running a similar set up and having the same problem with my PVR-150. My PVR-350's working fine in the same box though, so I'm sure it's something that needs tweaking on the PVR-150.

Thanks,
