Can't tune in some HD channels
#1
Have been successfully using ServerWMC for a while (months), without any real problems. All of a sudden, some weird behaviours: I'm not able to tune in *some* HD channels - the error in the log says "COM recorder says channel is not available ..." This is on Fox HD, which I know is good. I can tune it in on the serverWMC box in WMC (clients are separate boxes), and in QuickTV (SiliconDust live tv app), and also on the set top box (last one I have that's connected). At least one other channel is showing this behaviour too. There may be more, these are just the ones I've found. Can't figure it out. What I've done:

- re-scanned all the channels in the SiliconDust config app
- reloaded all the channels in WMC
- Wiped and reloaded the PVR DB in XBMC


Setup is ServerWMC is on a Windows 7 box, clients are latest Frodo XBMC release - technically openELEC

Any help appreciated!!

We have made some change recently to protect live streams. Make this change in the config.xml file and see if it restores the live stream for one of these problem channels:

<Decoy_LiveStreamProtectLevel>0</Decoy_LiveStreamProtectLevel>

then save the config file and restart swmc. If that solves the problem please let me know.

OK, seems like that fixed the problem (at least in my limited testing - the two known channels that failed before are now working)

Log file (editted for space): http://pastebin.com/Pc1dJ8xa

I did notice some errors were thrown, but did not really look too deeply at the log ...

I'm assuming this is still in diagnostics and there's more to be checked out? Let me know how else I can help!

You have six tuners all the same (same setup as me btw). Set in wmc each channel has a preferred order as to which tuner it is going to use (in wmc see channel>edit sources). Most of the time your channels have roughly the same order, but not always. When you try to tune to a channel it will go to the first in the priority list, if its busy it goes to the second, and so forth.

We implemented protection of a live stream from getting grabbed by wmc's recording service (when it is recording on the same channel) by assigning live-tv streams to the lowest priority channels by default. So that means that your lowest priority tuners aren't receiving those problem channels. When you made that change to the config you turned stream protection off so serverwmc was grabbing the high priority tuners and everything was working again.

So my guess is that some of your tuners at lowest priority aren't actually receiving these channels. Possibly resetting up wmc might solve the problem (might).

You can also set a less flexible method of protecting tuners by setting:
<Decoy_LiveStreamProtectLevel>2</Decoy_LiveStreamProtectLevel>

This method picks tuners closer to the top of the priority list, but won't be as successful at protecting tuners if the number of simultaneous streams and recordings is high.

Interesting. I *did* fire up 6 separate QuickTV sessions on the WMC server and tuned them all into the problem channel - no issues. This was while I was trouble shooting, so no clue if something else I did affecting the tuning issues.

Is there a way to selectively turn off HDHR turers? I could then check the problem channels from WMC to see if I can isolate any issues.

Yes, you can go to 'channels> edit sources' in wmc and change the order of the tuners. On one of the problem channels put the bottom tuner on top and see if wmc can tune to it. If it can, then try swmc, I don't think you will need to restart swmc for it to see the changes. This assumes you are keeping protecting live streams turned off (at zero).
