U4 - One tuner down

[nylonnet]

Since my U4 arrived and I set it up, I had a nagging suspicion that one tuner wasn't working but I never got around to a rigorous test.
But it did seem that my number of concurrent recordings maxed out too soon.

Last night I accidentally pressed the (?) button on the U4 remote.
It showed some very interesting system info.
I chose 'Devices' and my U4 displayed the list of my tuners - and there were only 3 of them! Aha!

Maybe the problem was the USB tuner dongle, or the little cable that fed it.
I replaced the tuner dongle with the one from my retired T3. No change.
I replaced the cable with the one from my retired T3 - and suddenly I had 4 tuners!

Maybe I had the only dodgy dongle cable in the history of Beyonwiz.
Maybe not.
When you get bored, you might want to check your tuner inventory.
