I cannot find any test pages other than this page.

https://bitmovin.com/demos/drm

I get the below error.

Video decoder or demuxer had an error with the content
(PLAYBACK_VIDEO_DECODING_ERROR)

When I try to play on netflix in edge I get error code d7361-1253, I am on clean install of windows 10 LTSC with updates applied.

If I disable playready in edge, both sites work but using the poorer widevine instead.

edge://gpu shows hardware playready support.

Any ideas?

I have fixed the bitmovin page by installing nvidia drivers not from windows update.

However netflix still has the error, netflix says windows 10 needs to be updated (help page for that code), so am I right in thinking that netflix doesnt support LTSC?
