So you're wanting VRD to fix the broken file? Sorry that's not something we can do. I suspect that this line in the Media Info is the culprit...
Color range : Limited
From what I can find this is apparently an encoder flag that prevents the video from being displayed as RGB. VideoReDo converts everything to RGB internally when displaying or recoding, so there is no way to convert or edit this file without it being corrupted.

It's a college football game recorded by someone I guess off of 4k tv, and downloaded off a torrent website because the first minute wasn't available on WatchESPN.
I just checked the video again in VLC player, and the picture is normal. I guess I felt that maybe I don't have it set to the proper encoder on in VR5 or VR6 to show the picture normally instead of gray.

It is the HDR10 PQ (REC2020 ST2084) Color Profile that is more likely the cause of your "greyed" video.
If you have access to an editing application that accepts LUTS (it's a good feature suggestion for VRD), you are more than welcome to use my custom 2020 PQ ->709 LUT that does an outstanding job. It is free.
Or, you can upload your HDR10 video to Youtube, and then download it again using 4K Video Downloader as an 8 bit MP4, and the conversion to proper color space will have been done for you.
Hope this helps, it has helped many others in your circumstance.

When working with HDR videos, i always use TMPGEnc Video Mastering Works 7.
There i do have found a Rec2020 to Rec709 LUT which works perfectly, because its actually costum created for handling 4K HDR Blu-ray's.
The costum LUT is named: Rec2020ToRec709_CSTCreativeSW
Using that one i sometimes only have to do some minor adjustments to the color and gamma if the video looks a tad to pale.
The LUT and also a few other costum created ones can be downloaded from the creators article:
The download section on his Google Drive account for his LUT's can be accessed directly at the bottom of the article.
