Playing rm file gives Exception

[ww220]

When I play some of rm or rmvb files with bsplayer 1.02 Build 812, I get exception that says: (Playing these files with RealOne Player Plus 2.0, build 6.0.11.868 has never been a problem)

BSplayer v1.02.812, Unhandled exception at EIP: 0209DFF3

Since this Exception ONLY happens with some of the rm and rmvb files,
I have already downloaded the latest realmediasplitter_20040125.zip
from http://prdownloads.sourceforge.net/guliverkli/ and successfully ran regsvr32 c:\windows\system32\realmediasplitter.ax

Can anyone give me a hint on what else I could do to solve this?
