Hi khotiburrahman,
I have been using SMPlayer on Linux Mint for several years now and have never had a problem updating from the ppa. If you haven't done so already you can add the ppa by starting "Software Sources" and then in the PPA tab choose "add" and then enter: ppa:rvm/smplayer. It will then ask you to refresh the cache and you are good to go.
