Hi Everyone,
About once or twice a day, I get the message saying that it couldn't detect a signal on a channel that I am attempting to record. However it appears the show did record.
To my understanding, if WMC cannot detect a signal, it tries using another tuner (if available).
This happens automatically, as a function of the interaction between the Ceton drivers and WMC. You don't need to worry about which of the four tuners actually got used as the "fail-over" tuner in case for some reason the hardware situation produces an unexpected "tuner not available".
You can see this in the History from WMC (go into the Recorded TV item, and then navigate up to "scheduled recordings" and then down to History). There's no real explanation for the inexplicable "tuner not available", but it does happen occasionally (even to me). WMC automatically tries to find another tuner and unless there is a true cable system outage where there's just no signal coming in on the coax inevitably the next tuner WILL find signal and be used for the recording.
I understand you sometimes get that message box in the lower right-corner of the screen if you're watching something (live or recorded), advising of this problem. But if you look at your Recorded TV list you'll see the WMC didn't depend on your responding in any way to this message box, in order to instantly "fail-over" to try and find an acceptable alternative tuner... which it virtually always does.
So by the time you look in Recorded TV, you'll see that this very program which failed on one tuner is actually already being recorded on some other tuner.
Not to worry.
My question, is there a way of changing the delay so that it waits a little longer before trying the next tuner?
No. And there's no reason for you to be concerned about whether tuner #1, #2, #3 or #4 are used for the recording. This is all automatic, and how it is designed to work.
Assuming your signal strength an SNR values are acceptable, any of the four tuners will produce a proper recording of any program from any tunable channel.
