Channel and Sub-channel suddenly not working

[johnsonx42]

originally I said your device isn't locking onto anything on that channel, but it actually doesn't report a lock or any signal for any of your channels. However, nextpvr isn't getting any data it recognizes from that channel:

Code:

2016-11-06 19:05:52.510    [INFO][1]    DigitalRecorder.StartStream(c:\nowhere\null.ts)
2016-11-06 19:05:52.510    [DEBUG][1]    Switching BDA graph to tune:

2016-11-06 19:05:54.935    [DEBUG][1]    locked=0, present=0, strength=0, quality=0   (took 0ms to check)
2016-11-06 19:05:54.935    [DEBUG][1]    File size is 0 bytes (non-existant)
2016-11-06 19:05:54.935    [INFO][1]    DigitalRecorder.StartStream() allocated handle: 0x5C
2016-11-06 19:05:54.935    [INFO][1]    DigitalRecorder.StopStream() handle: 5B
2016-11-06 19:06:00.016    [INFO][1]    DigitalRecorder.StartStream(c:\nowhere\null.ts)

in the five seconds between the message where it does the StartStream on handle 0x5C and then does the new StartStream(c:\nowhere\null.ts), that's where it's 'listening' to any data coming from the device... if it got anything it recognized, it'd log the service data table.

you can use TSCapture (http://www.tscapture.com/) to record 15-30 seconds of the Full Transport Stream for channel 25, and upload it somewhere so sub can access it. then he can see whether it's really getting no data, garbage data, or good data with something unexpected that's tripping things up.

Maybe a bad tuner?

What I did was to delete only one channel from one tuner. The scan would not find that channel again on that tuner. But when I went to watch live TV, I was able to get video and audio. The audio is good but video is jerky.

I am guessing what WMC does is to try the second tuner if there is no signal on the first. Might be a good idea for NextPVR if that is not already a feature. If it is then it does not seem to work for me.Probably what was throwing me.


When I get a chance I will test both tuners with signal strength in WMC.

Jerky video has gone away. I guess I had too many things loaded trying to figure out what is going on .

I will try both tuners on WMC signal strength when I get a chance

Suddenly all channels are back and working.

I think I am going to purchase a new turner just in case. I think I will try the HDHomerun
