Playing video/audio through SMB/DLNA shares are still too buggy.
File List is very buggy, some of the files gives gives error to open and some of the files (most likely if you have more than 256files on same share, rest wont show up or most of the list are truncated or cutted.)
If you seek a video from time to time, the video and audio gets out of sync and sometimes it cuts on some part of video.
A bug when playing a video through SMB and if network connection suddenly cuts, PS3 will freeze.
Redsquirrel87 is a tremendous developer for the scene and all, but I think he should wait a while before releasing a new version of his showtime player and not just release it every time he has a couple of updates.
