LAV splitter use in SageTV Client x64 9.2.6

[guho]

I've tried to set Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Frey Technologies\Common\DirectShow\CustomDemuxGuid to {B98D13E7-55DB-4385-A33D-09FD1BA26338}
but I can't get it to work. Could someone please tell me how to enable LAV Splitter for everything on SageTVClient x64 9.2.6?

Should the GUID correspond to LAV Splitter or LAV Splitter Source?

I also disabled Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Frey Technologies\Common\DirectShow\EnableSageTVStreamDemux. Nothing works so far. The reason I want to do this is that in certain cases, my mpeg-ts HDTV recordings freeze at the first frame instead of playing back.

I have the latest LAV 0.77.2 on my Windows 11x64 system. Thanks!
Edit: I set the registry value CustomDemuxGuid to {171252A0-8820-4AFE-9DF8-5C92B2D66B04}, which corresponds to LAV Splitter not LAV Splitter Source. I also had to downgrade 0.77.2 to 0.73.1 again (version that comes with SageTV) and it's working now!
