You replied:
“You have Hardware transcoding selected, as it tries to initialize the drivers of the three supported (Nvidia, Intel, AMD) starting with Nvidia.”

I have this problem also, how did this reply solve the problem?
Why is Plex looking for the wrong card?
Was I supposed to set it someplace?
If so where?

Thanks, Fred
