Again mirroring Andy's question, I am also having the issue of dynamiclinkmediaserver taking up a huge amount of energy and battery power while running LR Classic.

Per your requests though, I am running High Sierra (10.13.6) and LR Classic (9.3 Release). 

Activity Monitor is showing dynamiclinkmediaserver -> amecommand taking 454% CPU and is making my Macbook Pro run super slowly and export of a small gallery is taking over 4 hours. Advice on how to fix would be greatly appreciated!

I am also having this problem.
I came home after having been gone all day.  Computer was on, but Lightroom was not open.  dynamiclinkmediaserver.exe was blazing away using 100% of one cpu core, heating it up and running the fan.  I opened and closed Lightroom, with no effect.  Manually ending the process killed it.
Opening Lightroom again restarted dynamiclinkmediaserver.exe, but did not restart the high CPU usage.  Closing Lightroom this time also ended dynamiclinkmediaserver.exe.

Why was this process running without Lightroom even being open?

Windows 10 v.1909 Build [18363.900]
Lightroom Classic v9.1 Build [201911291132-64cf80b4]

Evan,

You should probably update to Classic 9.3 as there have been several fixes released.

I am running LR Classic 9.3 in Windows 10.  This is a problem I've only seen consistently recently.  If I export a folder of a few hundred photos and just a couple of small videos (H.264), the export eventually hangs.  the progress bar shows only 25-35% complete, and does not move.  The export destination folder has all of the photos and some, but not all, of the videos.  If I look at Task Manager, CPU is at 100% almost all of it LR Classic, dynamiclinkmediaserver, and NUMEROUS instances of  amecommand.exe.
