Hauppauge HVR plays back in slow motion.

[nbetham@…]

I have a Hauppauge HVR 1800 that when I try to load live TV or watch any recording in MythTv? it plays back in slow motion and the audio is very deep. But when I access this card from any other program it plays back fine. I have tried the most recent V4L drivers and even a more recent driver from the developer, neither have worked.

Analog on the HVR-1800 will not currently work due to a driver bug. Contact the v4l-dvb mailing list or kernellabs.com for more details.

After getting a more up-to-date feel from the HVR-1800 driver dev, we're both a bit uncertain about whether the issue is in the driver or in myth. Let's get backend and frontend logs of an attempt to capture w/ -v playback on the frontend and -v important,channel,extra on the backend.

Also, make sure you are using the most up to date version of the driver from:

​http://kernellabs.com/hg/~stoth/cx23885-api/

dmesg output (from the modprobe and an attempt to capture) may help too.

backend verbose mode output

mythfrontend verbose mode

dmesg output

I used the mkrufky cx23885-api driver version because the stoth version would not compile correctly. I am a bit confused about the dmesg output from modprobe, how do I execute that in terminal?

I have also found that after I watch live TV in MythTv? the problem propagates to all the other applications that use the analog encoder.

That last detail confirms it's a driver bug.
