I have a PC with 2x digitalnow 7164 twin-tuner PCIE cards in it, making 4 tuners total. It has been VERY handy.
Until a few weeks ago, scheduled TVSP recordings successfully used all 4 tuners to record from up to 4 TV channels at a time.
Now, it only records from 2 tuners, even though TVSP shows the tuners as OK in the Device Selection window.
Can anyone tell me how to debug, i.e. what to do next to find out what's going wrong and fix it ?
Here are a couple of producer logs in case that helps.
