Attached 192 bytes long 192.avi file crashes explorer.exe if fun_avcodec.dll is present in system.

fun_avcodec.dll is installed (at least) with samsung pc studio software for samsung mobile phones.

Tested with win xp sp3. Install samsung pc studio 3.x, open folder with 192.avi, explorer.exe crashes.

AppName: explorer.exe AppVer: 6.0.2900.5512 ModName: fun_avcodec.dll ModVer: Offset: 0000301a

Example path to .dll:
C:\Program Files\Samsung\Samsung PC Studio 3\fun_avcodec.dll

Rename fun_avcodec.dll to fun_avcodec.XXX or similar to avoid crash.

No idea if this is not a real problem (for samsung pc studio users) or if it can be exploited any further. Try and find out...
