With Brasero, I have been able to burn a "data disk" no problem.
But if I try to do a "video project", Brasero gives an error message: "Please replace the disc with a supported CD or DVD", yet, right at the bottom, in the window where you choose image file or disc, it actually confirms that it is a 4.4GB DVD and the space estimate predicts that about a third will be left blank after burning (well below capacity).
I have tried closing brasero, and restarting it, to try different blank discs, but to no avail.
All of this worked fine under the standard editions of Mint.
Also, when inserting other discs, at first it would acknowledge one was inserted, and now it stops reading/detecting that I inserted another one.
