Mplayerosx - Can't seek when watching rmvb files, rev 13 - Redmine

Can't seek when watching rmvb files, rev 13

I think there're still lots of ppl watching videos in rmvb format sometimes, just like me. I can't remember MplayerOSX lost the function to seek in rmvb files, while rev 13 just makes it worse: if you try to seek in rmvb, the whole player just freezes and you have to force quit it.
Please fix it because I really like using MPlayerosx rather than vlc, movist or plex. Thanks in advance!
