I asked this over six months ago and got no response so if it's ok I'd like to try again!
If I add, let's say, a video I downloaded from YouTube to Channels as a movie and don't give it any poster art and then view that title in a collection, it shows up as expected with no poster image, just a purple rectangle with the title of the movie file.
But if I then add that same movie to a virtual channel, it shows up in the guide with the poster art of a non-related movie I recorded from one of my sources!
Something has changed since when I first posted about this. Back then, the movies with no art would assume the art of whatever movie I had most recently recorded from one of my sources. That eventually stopped.
Looking at the dates of my recordings, the movies with no art are currently showing the poster of a movie I recorded on January 3rd. The next movie I recorded was on January 9th, so it seems something may have changed between those dates.
If no one else is having this issue and it's not worth tracking down exactly what happened, is there a way to "reset" the images my virtual channels use so I can see if they'll stay properly blank now?
Thanks for any help.
