- No, I have not tried WinTV 10 yet.
That's because WinTV 8 works with Win10 1909 and older perfectly fine on 100% clean ISO installs into the Surface Pro 4.
I went through the trouble of downloading each ISO (1703, 1909, 2004, 21286, 21354) and installing it fresh on the Surface Pro 4, wiping the drive clean, keeping nothing. Each time, I installed WinTV 8 with the noted issues or not.
2. Something was DEFINITELY introduced with 2004 and exists in 21354 still that causes the stuttering - Microsoft Windows-side!!!
I can install 1909 and WinTV and the tuner will work 100% fine.
2004 or newer and it will not work fine.
3. KEEP in mind, this stuttering issue affects other linked users and more who have USB A/V capture/TV tuner devices, too. In other words, IT IS NOT isolated to simply the older version of WinTV v8 vs 10.

"My Dazzle DVC100 always work fine with Windows 7/8/10 =<1909 until I installed 2004 and also get Inserted Frames with choppy videoplayback and distorted audio."
4. There are no other devices plugged into the 1 Surface Pro 4 USB port.
But maybe it could be USB subsystem issues in Win10?
Eg. https://www.reddit.com/r/AMDHelp/comments/fgpdy7/solved\_usb\_dac\_audio\_playback\_stutteringcrackling/
"I noticed that the DAC was plugged into a USB 3.1 Gen 2 port that is provided via the B450 chipset. Miraculously, switching to one of the two USB 3.1 Gen 1 ports that look to be provided directly via the CPU seems to have completely solved this problem."

- But just for giggles, and betting against it hard, I installed NextPVR and guess what?
The SAME STUTTERING issue occurs across all TV channels.
DEFINITELY NOT a WinTV 8 vs 10 issue, especially given the reports above from other users of other A/V devices that stutter with 2004 or newer.
