Windows 10: Davinci Resolve and H.265 videos

I have been using the free version of Davinci Resolve 16 to edit videos from my GoPro Hero 7 Black camera on a PC that is about 5 years old. I had installed the HEVC codec from the Microsoft Store and was able to process H.265 video with no problems. The system was underpowered to process 4K video so I bought a new system. It is a Dell G5 with i9 CPU and an NVidia RTX 2070 Super GPU.


I installed the HEVC codec on the new system. Davinci Resolve does not recognize that the HEVC codec is available. When importing H.265 videos, Resolve shows "Media Offline" on the video clips. I have seen multiple videos that show installing the HEVC codec, either the paid or free version from the Microsoft Store, enables Davinci to work correctly. I have uninstalled and reinstalled Davinci and the codecs My Windows 10 has all current updates installed. I have the latest version of the NVidia drivers and Davinci.


One other difference between the two computers is that the old one is running the latest Windows Insider version. The latest insider version broke Davinci. It hangs at "Loading Fairlight Page". Prior to that version, it worked flawlessly.


I spoke with tech support for Davinci Resolve and was told that I had to get the full version and that the free version does not support H.265. I asked him why it worked on my old computer and on multiple other systems, as seen on Youtube and other forums. He could not explain it and said that the free version does not include tech support so he couldn't elevate the issue.


Does anyone have any insight into this issue? Why would it work on a 5 year old system with an i3 CPU and an older NVidia GPU?


I really don't want to spend $299 for the paid version of Resolve when it appears that the free version should work.

Finding which videos in a directory of various videos are H.265?

Ah!

Using that and this website, it appears I have three types:

1. 5634504D-0000-0010-8000-00AA00389B71 (MPEG-4 Part 2)
2. 34363248-0000-0010-8000-00AA00389B71 (H.264)
3. Unspecified

I'll presume the Unspecified ones (there are dozens of them) are H.265.

This is a sample of the 'Unspecified' video files in question (from MediaInfo):





It appears I need a new way to differentiate them, beside the 'Video compression' column.

I'm not sure what your 'unspecified' types may be. I specifically created an H.265 encoded file for my screenshot and it shows as compression type {43564548-0000-0010-8000-00AA00389B71}
