"The tuner being used for LiveTV is no longer available"

[MCEabused]

Hi
I'm getting this too on win7 64bit in Auckand NZ, I just assumed it was win7 wanting to be activated.

[BigMoose]

I just have to start live tv, no channel changes or anything. Using a hauppauge hvr4000 watching dvb-s. Win7 x64 pro. Same machine that's run previous versions without seeing this problem. I have rebooted and it still happens - but I can't remember if I changed channel first or not after the reboot...

[johnsonx42]

It does appear that other things can cause this to happen beside changing channels while in LiveTV. For my system, changing channels will do it every time. But just now I tried Live TV after several recordings were completed this evening, and it's failing the same way yet I'm about 99% certain no channel changes were done earlier in the evening. The error in the log is the same though, it gets a failure when it tries to renew the lease on the capture source.

Sub, maybe more logging about what is going on at the lease renewal stage?

[johnsonx42]

I think this is probably part of the same issue, or closely related anyway (plus I'm afraid if I start one more thread about a problem in NPVR I'll get perma-banned!):

The new feature to move a recording to another tuner to allow live tv to continue doesn't seem to work completely in all cases; it goes through the motions, but at the end of it all the lease renewal fails and live tv quits. Here is the relevant bit of the log:

Code:

Then after that, when the recording is supposed to end, it doesn't really end anything:

Code:

2010-08-12 19:30:00.101    [DEBUG][6]    Stopping recording (4250). Past end time of recording.
2010-08-12 19:30:00.101    [INFO][6]    DigitalRecorder.StopStream() handle: 2

Nothing about any graph actually being stopped... it's gotten confused about which stream handle is which I guess. As I write this, this recording is still running; it shows as a Ready recording, but the graph is still writing data to the file. 30 minute recordings on this SD channel are normally ~600MB, and it's up to 2.6GB and growing... I'll probably have to reboot the thing to kill the graph.

The relevant NRECORD log is attached.

lol - nah, you dont have to worry about that

Unfortunately I've been stuck on day job stuff the last couple of days, so I havnt had a chance to look into it yet. Weekend rapidly approaching though...

[johnsonx42]

well the day job stuff really does have to take precedence... my wife always gives me *that look* if I'm messing with NPVR and the forum during business hours.

I hope you never feel my various posts and follow-up posts are meant to bug you, it's all just about providing as much info as I can.

[BigMoose]

I was playing around with nPVR again to see if I could get live TV stable and after a reboot or two and reregistering the filters it did play live TV fine and I could change channels and watch for as long as I like - but exit live TV and next time you try and you're back to this error. So the earlier comment about changing a channel is right. Dont think the filter reregister made any difference. So really this is confirming everything already said in this thread, restarting the recording service seems to make it work next time, but a channel change will kill it for the time after.

[donschjr]

Add me to the list of people getting this.

[johnsonx42]

a little followup to the issue I reported in post 14, I have found that restarting the recording service is sufficient to kill the run-on recording that occurs in that scenario (and has occurred pretty much every time since then).

[mvallevand]

Not quite. The previous "Past end time of recording." error when stopping a recording can trigger a crash when starting livetv or the next recording on that tuner. Restarting the recording service will restart recording of the live tv program which you then need to cancel, causing another crash and so on and so on. You need to start the service cancel the program you don't want and then restart the service.
