I'm having a bit of a problem with VobSub when using BSPlayer. VobSub isn't activating when I load a .ogm file in BSPlayer. VobSub activates just fine when I load a .ogm in Windows Media Player...but I don't like WMP

I'm using BSPlayer v1.00 RC1 and VobSub 2.23. This probably isn't enough information to work off of so if I left anything important out just tell me what it is since I'm not really sure what information would be pertinent to this problem. Thanks.
