after i installed SMPlayer Version: 18.2.2 (revision 8937) on Linux Mint 19, Cinnamon, i cant use my old configuration (from Mint 18.2, Cinnamon) - the Player wont play any video, just load it and stop.
So i created a clean config from scratch. now it works.
Thanks, have a nice day
Edit:
My OS: Kernel: 4.15.0-36-generic x86_64 bits: 64 Desktop: Cinnamon 3.8.9 Distro: Linux Mint 19 Tara
After i added the repository ( https://www.smplayer.info/downloads.php ) i got the newest version of SMPlayer, but now there is the former "bug": hopping window after close SMPlayer ( https://forum.smplayer.info/viewtopic.p ... 736#p16736 ).
But for Linux Mint 19 (based on ubuntu 18.04) there is only an old version available (18.2.2) ( https://software.opensuse.org/download. ... e=smplayer ).
Edit 2:
My fault, i forgot the signature key
All done for now.
