SMPlayer can't play next video automatically

[8hatchery]

Hello, guys. New guy here, really glad to be a part of this community. I installed my mint 14 couple weeks ago, it is so great, much better than the current Ubuntu.

And I am trying to find a good media player. It seems that VLC and SMPlayer are the best. But VLC has audio and video sync problems from time to time on my computer. So right now, I only use SMPlayer, but it seems that SMPlayer can't play next video on playlist automatically. I can't find any solution through googling, and it seems that not a lot of people are facing this problem.

Can someone help me on this problem, or recommend some other better media players?
Thank you!

Edit: VLC's playlist is working fine. And just tried Gnome mplayer, it also won't play next file. It seems to be a mplayer problem, rather than front-end gui problem.

I guess not many people have this problem, or don't get bothered by it.

I kind of solved it, but not ideal solution. It turns out that the default smplayer in apt-get uses mplayer2, so I downgraded mplayer from mplayer2 to mplayer. Now, the playlist problem is solved, but I hope mplayer2 can solve this problem soon.
