Commercial software,
down the toilet.
You said that VLC worked for you 2 days ago.
If I was you I would try the latest version of VLC.
Check how old is your VLC, and if there is any later, give it a try.
VLC team would ask you to do the same before reporting a fault.
Their downloads (users) count in millions, this is maybe why you don't have personal attention from them.
Try both 2.2.5 and 3.
