I haven’t run Plex Server on Windows for a while, so I may not be the best to help but I’ll give it a shot since no one else has chimed in. I didn’t have to run Plex as an admin on Win, and I had Live TV/DVR working. Plex does need to be able to create/write to a “.grab” folder in whatever folder you have selected as the target library for your recordings, and then needs to be able to create/write subsequent folders when it moves completed recordings from “.grab” to the show’s destination folder. There isn’t enough info in your post to know if the problem is when starting the recording and writing to .grab, or at the end of the recording when it is moving the file.
To simplify things make sure you have the commercial skipper turned off. Would you be able to post your log files, or at least the section around where errors are produced? (If a Plex representative picks up this thread they will ask for full log files.) Typically with Live TV the errors people post are with either not being able to create files, or not being able to move files, but you’re seeing something with not being able to open files.
Also, 1.18 is a beta. You may want to downgrade to the latest public release which is 1.17.0.1841. At a minimum I know there are issues with 1.18 Live TV pixelation and skipping.
I have tried all combinations of DLNA/HWAccel/CommSkip enabled disabled etc.
I have verified access rights as well, including granting Full Control to Everyone
This happens on multiple versions of Plex. The only thing left to do is downgrade Windows 10 to 1703, and I am not willing to do that, as it is a temporary fix.
Thinking of installing Ubuntu server on this box. My current Ubuntu box is maxing out on CPU usage when I am recording 4 shows at once. I am concerned that the once I try to do playback along with 4 recording in progress, things may not be all kosher.
After loooking at your logs I’m not positive that it’s just a permissions error. I do see an error at the start where it can’t verify space availability in .grab, but it proceeds. The error that I THINK is root cause is as follows.

It can’t identify the sample rate, then gets an invalid codec parameter error (possibly the sample rate parameter not identified but is needed for the transcoder.) The subsequent set of errors regarding not being able to open files is because the files were never created in the first place because of the transcoder error. There is a similar set of errors where another show was trying to start recording at the same time.
Does this only happen when two recordings start at the same time? I found this thread where others were getting the same error, and they worked around by having one show start a minute early. Here is another with a different resolution.
Sorry, I can’t find a definite fix and haven’t had this problem myself, but perhaps this will get some thinking in a different direction. I personally do rather like the idea of Ubuntu as the base OS install. You can always run Win in a VM if it is needed.
Thank you for the response. I gave up Windows 10 DVR. Just finished rebuilding the machine with Ubuntu 19.1. Will install Plex later this week and see what happens.
