I have a Window 8.1 machine with an Intel Core i5-2310 CPU and an nVidia Geforce GT 240 discrete GPU. Both onboard and discrete are enabled in the BIOS and Windows Device manager shows drivers for both the Intel HD Graphics and NVIDIA GeFore GT 240.
However Channels DVR shows "Software’ for the transcoder. Any ideas why?
Please run an HWE test. Open PowerShell to run this command, then open the DVR log and copy/paste the new “HWE” entries that appear.

Looks like you might need a newer nvidia driver.
Is the nVidia driver preventing it from using the Intel driver? The nVidia card is fairly old, so I think the latest driver is v342.01.
No, the Intel driver is also failing for some reason. I’m not sure if perhaps the integrated GPU is disabled when another GPU is present?
We use two different APIs for intel h/w transcoding (one from MSFT and the other from Intel), and both are failing:
