Build 21277 - Hauppauge WinTV software stopped work

Thanks!

My hauppauge wintv 950 tv tuner stopped working since 2004 19041, so been waiting awhile for a fix.

Worked fine from xp to 7, worked in fresh installs of wintv 8 into fresh installs of 1903, 1909, a/v stutters in 2004, but driver won't install right in 20h1, so the issue pre-dates the 21277 version of this thread.

Hopefully, both the driver installation issue and a/v tuner stutter issue are fixed, too!

Hi,

Drop us a me a note to ******@hauppauge.co.uk for my attention, I'm sure we can get it up and running.

This is the latest driver to try is here:

https://hauppauge.s3.amazonaws.com/drivers/wintv-hvr-930c\_driver\_5\_2020\_0406\_38260.exe

The HVR-955q is the late or better option would be the dualHD or quadHD

the 950q got better chipset and support QAM that what the q stand for

Hi,
Perhaps. But a 15 year old 950 vs 11 year old 950q suggests that if both models were working in WinXP through Win10 1909, but not with 2004 or higher, then MS screwed up something that has worked perfectly fine for a decade.

The first obvious hint is in 2004, where the drivers install, but the A/V stutters. Something new added/adjusted within Win10 2004 is causing this stutter, similar to this thread's issue.

LatencyMon shows wdf01000.sys is the main detected file leading to high latency in 2004, much bigger than in prior win versions. Something in Windows changed to cause this (Hauppauge had previously posted a suggestion to try and turn off Core Isolation as a fix - didn't fix the problem).

...

Then in 20H1, the drivers don't want to start up - obviously something within Windows changed for the worse.

This device cannot start. (Code 10)

The problem may have stemmed from a point earlier than 2004.

For example, https://answers.microsoft.com/en-us/windows/forum/all/windows-10-build-1903-hauppauge-wintv-quadhd-tuner/c1d9f0cd-d03c-4022-bc60-04dd9caf1971
This person had an AV device issue as early as 1903.

This person's issue began with 1909.

And, it is not related to simply 1 Hauppauge device as other A/V devices appear to be negatively affected.

...

So, it is a problem that's wider than just 1 device since a number of users with different A/V devices have problems since 1903.

I'll try the 3rd party programs noted, but it doesn't address the issue directly of many different A/V devices not working with many other users after something changed within Windows.

Thanks!

My hauppauge wintv 950 tv tuner stopped working since 2004 19041, so been waiting awhile for a fix.

Worked fine from xp to 7, worked in fresh installs of wintv 8 into fresh installs of 1903, 1909, a/v stutters in 2004, but driver won't install right in 20h1, so the issue pre-dates the 21277 version of this thread.

Hopefully, both the driver installation issue and a/v tuner stutter issue are fixed, too!

You issue is diff then are also your device it very old date back 15 years if this is WinTV 950 before 950q model

By have try test any 3rdparty apps like SageTV or NextPVR
