seems more of a codec problem than a file association problem
if it is not (and ur 100% sure) try putting this in a file named ogm.reg and execute it:
Code:
REGEDIT4
[HKEY_CLASSES_ROOT\.ogm]
@="OGG.Video"
"Content Type"="application/ogg"
[HKEY_CLASSES_ROOT\OGG.Video]
@="OGG Video Container"
"EditFlags"=hex:00,00,00,00
[HKEY_CLASSES_ROOT\OGG.Video\shell]
@=""
[HKEY_CLASSES_ROOT\OGG.Video\shell\Open]
"EditFlags"=hex:01,00,00,00
[HKEY_CLASSES_ROOT\OGG.Video\shell\Open\command]
@="C:\\PROGRAM FILES\\BSPLAYER\\BPLAY.EXE \"%L\""
[HKEY_CLASSES_ROOT\OGG.Video\DefaultIcon]
@="C:\\PROGRAM FILES\\BSPLAYER\\BPLAY.EXE,0"
