Build 21277 - Hauppauge WinTV software stopped work

1. Tested SichboPVR.
       Same result as before - A/V Stuttering across all channels.
2. This issue is not isolated to 1 single, older A/V device.
       It affects newer A/V devices as well as noted across the other complaints of 2004 causing A/V stuttering with USB connected A/V devices.

    This immediately suggests that there is something wrong going on within Windows itself, perhaps in the USB subsection or related services. Because even playback of media on a SD card was noted by one user to cause stuttering as well in 2004, this is likely not a 1 old device problem - it is a widespread problem introduced deep within Windows from 2004 onward.

3. I know I can go with Linux. Or simply 1909 Windows.

    But the idea of the Insider program is to FIX THE BUGS, not to turn a blind eye.

2: I never said isolated to 1 single, older A/V device I said chipset which in many other brand TV Tuner even Capture device there could be a pacific legacy feature that no longer being support that my have causing this that no longer working in Windows 10 higher then 1909.  But like I said highly doubt MS will address this if that where the case that would be like get back the Hardware Abstraction Layer for DirectSound and DirectSound3D that was remove many year ago in Vista and believe me a lot us whine cry about which turn our Creative Labs Sound Baster card in to paper weight.

It not about "not to turn a blind eye" if my dualHD or quadHD which are USB are working just fine if that there not the case you can bet I be all over this with MS and Hauppauge to get to the bottom of this, Oh by the has new Empia tech chipset in case you didn't know this it not the first Empia tech chipset that has had OS incompatibility like back in day of XP with going newer OS if I call right the HVR-850 had all kind of problem too more so 64bit OS.

I have wide number of Hauppauge TV tuner many of which are obsolete from old day ISA to PCI a few USB Hardware MPEG Encoder you may have even seem my nickname SHSPVR or SHS on PC TV tuner or TV Analog Capture relate forums.

As far I know you seem to be only one that has this issues and I do keep eye across all major PC DVR software forum SageTV, NextPVR, Plex and other OS and many other place too.

You need find other get to joint the discussion did say newer HVR-955q was also having this problem being it is much diff chipset then the 950q

1. I DID POST INTO A NEW INSIDER THREAD!
      THE Admins COMBINED threads back into this one.
2. I DID POST into the FEEDBACK HUB, TOO.
3. Just because a newer version of Windows comes out shouldn't mean perfectly working A/V devices that have worked for years without an issue should suddenly start stuttering, like many others have noted. 

   I can understand if 1 device stopped working, but multiple different A/V devices?
   This strongly suggests there's a bad change within Windows that negatively affects devices.

That all I want to know dcdc888 if NextPVR was doing the same thing as just case in was dotnet thing and besure pleases test SichboPVR then this may point to a driver or hardware firmware issues or OS incompatibility with newer builder of Windows 10 my guess is that related to Empia tech em2883 chipset just like what on your DVC100 and many of the other brand TV tuner that ware mention in Born's Tech and Windows World forum post at bottom.

If was you I would just ditch the old 950 as I highly doubt that hauppauge is going put any resources to fixing a 15 year old device as it be that chip manufacture would have to fix there firmware if that where problem is at, you should think about get newer WinTV-dualHD which I test on my Windows 10 Preview builder box as well as quadHD and many other sorry I don't an old 950. You know you could always go to Linux.

1. 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."

5. 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.

What you are experiencing is a different problem than the original post. For retail builds, I suggest you contact Customer support. For issues with Insider builds, please file feedback in Feedback Hub. If you wish to continue discussion here in Answers, please start a new thread. 

Please note that if there is a new version of the software, I would recommend updating to it on newer Windows versions. Just because something worked on an older version of Windows does not mean it will continue to work on newer versions.
