Under Windows 10 with NextPVR and WinTV:
* By default sets the TV channel video type to MPEG-2. That works fine for the SD channels and the 8 HD channels that are MPEG-2. I have to manually set each of the 95 HD channels that have type MPEG-4 to the correct value or the channel is not viewable.
* Plays only subscribed to TV channels that have the "copy freely" flag set. The 23 channels have the "copy once" flag are blocked
I thought the purpose of the DRM flags was to control recorded HD content. Why under Windows 10 are they used to control content that can be watched also?
Was Windows Media Center so much better because Microsoft spent a lot of money on it? If so was it that they calculated that the investment was no longer worth it considering that most people seemed to have gone to video streaming.
The DRM flags are for viewing and recording.
"Copy freely" means it can be viewed or recorded on any device.
"Copy Once" means it can be viewed or recorded on any device meeting the DRM requirements. The recordings can only be viewed on the device that recorded them.
"Copy Never" means that a program can be viewed on any device meeting the DRM requirements, but cannot be recorded.
In this context, WMC Extenders effectively are treated as part of the host WMC machine. Copy Once and Copy Never streams are encrypted prior to transmission, so without the necessary DRM components they cannot be viewed or recorded. It isn't a matter of the software enforcing DRM, it is a matter of the software lacking the necessary DRM components to decrypt the encrypted streams.
Local networks are almost always "copy freely"
Pay Per View movies and events are almost always "copy never"
Other cable channels will typically be "copy freely" or "copy once" depending on the cable provider.
None of this changed with Windows 10. What changed was the decision to (not) include WMC (and the necessary DRM components) in Windows 10. It was the only DVR to support DRM. Since the Windows 10 release SiliconDust has started a Kickstarter campaign which is still in development. I believe they have a Windows 10 client that is in beta that has support for DRM, but no official releases yet.
There has also been a project that allows you to install WMC on Win10, but it us also unofficial and could be disabled via Windows Update at the whim of Microsoft.
