OK, just muxed an ogm file, XviD, MP3, two embedded subtitles one in romanian, one in french. Installed Gabest OGM splitter. Playing OK the file as long as the video was in the same folder with the external subtitles. But didn't detected the internal ones. Splitter does however detect them because MPC (Gabest player) detect and display them OK. Once moved (just internal subtitles) BSPlayer crashed.

AppName: bsplayer.exe AppVer: 2.1.1.940 ModName: bsplayer.exe
ModVer: 2.1.1.940 Offset: 001188c6

Uninstalled Gabest, installed OGGds0996. Smooth. Nice. So, for now, the score is 0:2 for BSPlayer. No Haali full support, no Gabest full support.

i installed OGGds0996 and now everything seems normal
