Status: Unavailable (ServerWMC Backend error) == Friendly Fire

[markshu 7]

I finally got around to installing ServerWMC just to see how the live tv streaming worked to remote clients. I did this from an RPC session via a local hotspat during lunch, and could not get any status except 'Status: Unavailable (ServerWMC Backend error)'. Took me a while, but after reinstalling ServerWMC and digging through the MBS logs I saw that it was failing in the GetStatusInfoAsync::TunerStatus call ...

 

... and right at that point I remembered I had swapped out one of my four Avermedia HD Dual tuner cards last week with a ATI graphics card so I could play around with MadVR ...

 

... and I had neglected to rescan my tuners in WMC, since I still had 6 available after the swap and WMC didn't care as long as I didn't try to record 7 shows at once ...

 

... and that it was my own d*mned fault there was no tuner status coming back from ServerWMC (even if MBS was tossing an unhandled exception in this situation).

 

Chalk this one up as User Error.  Hopefully this little story will save someone else a little time.

I don't know if it will help anybody either but I enjoyed reading it == friendly return fire

Krusty, are you able to offer more precise info of the problem? For example, suppose server wmc is running but the tuners aren't configured in wmc. Could it say something like ServerWmc unable to connect to Windows Media Center. 

 

Or if server wmc is down, the plugin will not be able to talk to it, so it could say something like "ServerWmc service unreachable"

Here's the section of the log where the exception is thrown:

It looks like the message is just passed through verbatim.  I think a better error status would be something along the lines of:

 

"ServerWMC tuner status unavailable. Please check TV tuner configuration in WMC TV Settings."

 

 

[krustyreturns 191]

@@Luke, if no tuners are configured in swmc it won't run, it states the problem in a popup and tells the user to configure wmc and try again.  This case was different as he had some configured and some not - and that's a first so far as I know.  I agree swmc could have been more helpful in diagnosing the problem, but we pick and choose our battles.  Next time I add a tuner to my devel machine, I'll run it before configuring to check the problem cause.

... and just to confirm, rescanning the tuners in WMC did indeed fix the problem.

Had the same issue. Refused to go away with a re-scan.

 

What fixed it was resetting WMC itself (which I probably needed done anyways) via the following:-

via cmd:
C:\Windows\ehome\mcupdate.exe -MediaCenterRecoryTask

Note that this clears EVERYTHING in WMC, resets it to pre-setup status completely.
