2004 Breaks My TV Tuner

I've tried twice to install build 2004 on my Core i7 HP Pavilion since
it finally became available. Each time it causes my Pinnacle HDTV Pro
Stick 800e USB TV tuner to produce unwatchably choppy video and audio.
I KNOW something 2004 is doing is causing it because I've tried
installing another PVR software product (NextPVR as opposed to
SichboPVR) and get the same results. I tried updating the video drivers
and running sfc /scannow and neither of those helped either. Rolling
back to 1909 gets it working perfectly again. Well, I was able to live
perfectly happily without 2004 up to now but if anyone out there has any
other ideas I'm all ears.

Task Manager ? See any process besides the Tuner process which is busy ?

You can also use Sysinternals Process Monitor, and see the
what pile of things are flying around on the machine.

The nice thing about modern TV signals, is that the digital packets
are already compressed, and can be written to disk directly. If not
watching TV, it's easy for the computer to deal with. The video card
can also have a DXVA2 decoder for the packet and allow display with
almost no CPU work at all. In Task Manager, in the GPU tab, you might
see a little activity in there, representing the GPU contribution
to viewing an image.

It's possible to require more CPU, such as if you don't have a video
card driver installed, and the Microsoft Basic Display Adapter is being
used. There's be no GPU section in Task Manager. Decoding would be with
the CPU. None of this would cause a Core i7 to rail, as it should
have enough horsepower for this. If the image needs to be resized to
full screen, and video card acceleration was completely broken, rescaling
with a CPU takes more compute power.

Have a look in Device Manager and make sure all the drivers
are installed.

My TV Tuner is one hardware device, which Windows 10 does not
load automatically. Apparently Hauppauge didn't send a driver
to MSFT. On Linux, I have to install the firmware manually, as
it is not in the Repository tree.

You should be able to sniff around and learn more about what
is going on.
