Livestreams can't play on Firefox (Windows 10)

Hi there,

I tried installing the KLite codec pack, and then installed SPV4 on top of it. Excuse the naivete if it's blatantly obvious.

In essence, any streams fail out.

I'm attaching my Codec Tweak Tool log. I tried to attach dxdiag but the post was too long.

I'm on Windows 10 latest version, and I can provide more information if required.

Firefox does not use the codecs from K-Lite. It only uses its own internal codecs and the standard codecs from Windows.

The log shows that Microsoft DTV-DVD Video Decoder is disabled. That may be the cause of your problem.

You can re-enable it here:
