Using R5C7, my PVR-150 MCE only records mono on channels I know are stereo. I also have a PVR-350 and it records stereo on the same channels. Here's the output from "ivtvctl -d /dev/video1 -Z":
Quote:
ioctl VIDIOC_G_TUNER ok
current audio mode : 1
(stereo 1, lang1 3, lang2 2, mono 0)
available subchannels: 0x1
(stereo 0x2, lang1 0x8, lang2 0x4, mono 0x1)

/dev/video1 is the PVR-150. When I do this for the PVR-350, the only difference is:
Quote:
available subchannels: 0x2

So it seems that the PVR-150 isn't recognizing that the channel is stereo.

I did some testing to try and figure out what's going on. I did clean installs of R5B7 (IVTV 0.4.3) and R5C7 (IVTV 0.4.4) and both have this same problem. I also did a clean install of R5A30.2 (IVTV 0.4.0) and it did not have this problem. I upgraded to IVTV 0.4.4 in R5A30.2 and the PVR-150 still detected the stereo channels.

I'm not sure what to do now. Here are the relevant lines from /var/log/messages in R5C7:

I can also post the log information from the working R5A30.2/IVTV 0.4.4 installation if that helps.

Thanks

You can try ivtv 0.4.6 by following the CompileIvtv directions on the wiki and replacing references to 0.4.4 with 0.4.6. The only caveat is that I've seen some nasty video corruption with 0.4.6 that I don't see with 0.4.4. However it's worth a shot since it may work better for you and it's equally easy to revert to 0.4.4.

OBTW - Test with 0.4.6 across a substantial number of channels for at least a couple minutes each before you commit to using it for any recordings that you care about! I saw particulalry bad behaviour in the 60's of us-cable-irc.

IVTV 0.4.6 didn't fix the stereo detection problem for the PVR-150. It didn't cause any new problems either. Everything seems the same as it was with 0.4.4. I don't think the IVTV version matters since the card detects stereo in R5A30.2 regardless of the version.

I just got a new PVR-500 and it has this same problem with both tuners. In R5C7 with IVTV 0.4.4 or 0.4.6, it detects all channels as mono. In R5A30.2 with IVTV 0.4.4 or 0.4.6, it detects the stereo channels correctly.

What's changed between R5A30.2 and R5B7/R5C7 that could cause this? It doesn't seem to be the IVTV version and I don't think it's MythTV because it does the same thing when changing channels with ivtv-tune. Is anyone else having this problem?

I'm running R5C7 and using the pcHD 3000 card. Stereo works fine on the HD card. I just added a PVR 500 and upgraded IVTV to 0.4.6 to correctly identify the PVR 500 with the new tuners.

The HD 3000 still detects and plays stereo channels but the PVR 500 is mono only. I thought maybe the card only supported mono until I found this thread. I'm glad to know it can do stereo, now it's just figuring out what the problem is...

By the way IVTV 0.4.6 does not seem to cause any video problems for me.

Did anyone figure out a solution to this? I'm experiencing the same problem.

I think this is fixed in R5D1 but I never found a solution for R5C7.

Alright. I'm still on R5B7, only because I never found a compelling reason to upgrade. I'll upgrade at some point. Of course, that would be easier if my projector (the only monitor I have to connect directly to the machine) was working, but hopefully that'll be fixed shortly.
