Hmmm... in addition, when trying to play original in DSPlayer I still get the cache errors... this even disabling cache and deleting the directory reference in settings.xml. This doesn't happen if selecting DVDPlayer.

Here's the log (I didn't take debug as the warning and errors come out anyway, if you need debug just let me know):

I have Force Prompt Quality activated and "Never transcode" deactivated.

By the way, if you activate "Never transcode", it transcodes even if selecting "original" in the quality prompt. In both DVDPlayer and DSPlayer. This leads me to believe that the issue with cache wasn't solved, it simply hid behind me selecting original and the plugin serving a transcoded version anyway.
