I downloaded Process Explorer but there are so few processes running - none of which seemed relevant.

You mention few processes so you probably need to go to File -> Show Details for All Processes in order to actually see every process running on your system.

Did you perform a search for any of...

A big thank you both for the support. I think the take away is set the audio to stereo in WMC setup ONCE and never mess with it. I'm not sure why changing it to 5.1, then back to Stereo broke it and couldn't be fixed, BUT very happy with a fresh install that I have a perfect working WMC on W10....

I'm sorry, I don't have anything constructive to add other than to advise that an in-place upgrade is a terrible idea.
You should really consider backing up your critical data.
Then, format and do a fresh install of Windows 10.

Otherwise, this won't be the only issue you run into.
In place...

Discoveries after 3rd day of fixing (probably mostly true-from scribbled notes):
Starting with no PrintReady (PR) installed:
First time - ResetDRM, uninstall WMC (reboot), install WMC, LiveTV works!. Using remote, changed cable box to On Demand channel and started receiving PlayReady errors. After...

You still have to refuse the Microsoft guide download to proceed with setup, even if you are not using EPG123.

After a lot of trying I have managed to get Intel to admit that they 'forked' development of the UHD driver after Gen 10 CPUs
Gen 7-10 UHD is fine including latest version updates, but Gen 11-13 and I believe some of the newer NUCs fail to black when switching channels with WMC full screen.

Thus...

I don't play recordings from network drives, so I'm not sure about your issue, but if you somehow changed your recording drive to be a network drive, that is not considered to be a good idea.

I did a load of testing on this and documented it here:

TLDR:
The last combination that Xbox extenders worked on without problems was Windows 10 V1511 and WMC V12.

Even then, there were hoops to jump through.

Third party extenders like the Ceton Echo don't work in any useful way on Windows 8 or...

I've got a Hauppauge Quad HD PCIe DVB-T2 card in one of my PCs. It works well but as you may be aware, the recordings only have stereo sound in the UK because there's no codec available for WMC to support the ridiculous audio standard we use on DVB-T2 here.

I've got four Hauppauge WinTV Starburst...

I think vanilla Win10 will have problems playing wtv files without installing the Windows DVD Player that gets installed with 8.9.x. The DVD Player provides proper drivers for MPEG2 decoding.

I've been doing some more research on CPU-GPU matching to avoid bottlenecks and found a calculator on PC-Builds.com which seems to support what I've read so far.

It appears to confirm that an ideal match for my i9 10920X would be something like the AMD Radeo RX6700 xt, which can be had for about...

It's been my understanding that Windows 10 (1511) was the last version of Windows that had all the necessary components to record and playback protected content.

Those that use that version use StopUpdates10 to lock it down.

problem resolved -- although ehshell with remote worked perfectly, it appeared that ehshell.exe did not fire up if green button on the remote was used to acheive the fire up

this was because the driver for the IR receiver was not initiated.
To initialise the Human Interface Device {HIM} it is...

I can't add too much about the codecs, but in the past I found Shark007 able to correct some issues and add codec compatibility within WMC. It has (did?) some recommended settings specifically for WMC.

For the HDMI switching issue, I had the same problem a long time ago and found that you need to...

Hi all, I’m using dvblink for iptv v3 with w10 and it’s working very well. The only thing I can’t get working are the subtitles. I’ve tried a couple different codecs. No joy. Any one have any tips for me ?

The problem came back and I never figured it out until just now. I finally fixed it by replacing my old nvidia 1050ti video card with an AMD RX 580. The 1050 ti worked fine in every other situation, so I guess it must have just been some strange interaction between WMC and my specific video card.

I had this and found it was using the default MS graphics driver.

I installed the one from the card vendor and it fixed it.

Thanks for the tip. This apparently fixed my issue! :thumbup:

Fox NFL Playoff games and the Super Bowl will be available in 4K through several Fox Sports distributors, including Altice Optimum, Comcast Xfinity, Cox Contour TV, DirecTV, Dish, FuboTV, Verizon FIOS and YouTube TV.

Thanks for the tip. However when I go to Settings>General>Windows Media Center Setup, it's not one of the choices listed. There's no mention of PlayReady. It's the WMC version 8.9.0 that I downloaded from your fantastic website. Thank you so much for all you do!

I do wish that someone could modify...

There's a good write up about this topic on Techchradar here: although its a bit old now, given that WMC is unsupported I don't expect MS will invest any time ensuring that it works on ARM.

Here's an extract:

The way Windows emulates x86 applications in software on...
