I did an upgrade to Windows 10 to get my system activated - then I did a fresh install from an ISO.
I did restore some of the settings from the previous Machine - i.e. Appdata folder etc which may have caused an issue.
I also updated from MC 20 to MC 21 as well but MC 20 was still installed.
EPG is fine.
I also reset all TV Settings and started again to see if this was the issue.
As you say all tuners show as IDLE when I look at the Status with the Program it is meant to be recording listed at the bottom:

OK so I have just:
1. Uninstalled MC 20 and MC 21 and deleted the C:\Users\User\AppData\Roaming\J River folder
2. Reinstalled MC 21 and Restored the Library
3. Alas the problem persisted.
4. Turned off Windows Firewall.
5. Launched MC 21 as Administrator.
6. Alas still no recording.
7. Launched channel - same black screen but this time Quality 100 and Strength 75!
8. Exited MC 21 and uninstalled the DVBSky Devices (including Drivers) from Device Manager. I already had the latest drivers from here:

I cry
I do have a USB DVB-T2 Device - I may try that later to see if I have any luck.
