playlist play-error

[t0bias]

on playing an playlist with bsplayer i encountered a strange error:
the files all play perfectly, if you load them clip by clip.
if i try to play them in a playlist, the player stops always after the first file and says something like
improper file format ()
i tryied this with like hundreds of clips, always the same..
anyone got an idea, or a suggestion?

thanks alot!!
