--- Comment #11 from Bruno Jesus 00cpxxx@gmail.com --- Wine does not provide any codec that can compress in 24/32 bitcount. You have to install a codec like Xvid, Indeo, Lagarith, CamStudioCodec or any other in order for the program to be able to do something.
After installing the codec go to Options->Video Options to select it.
But there seems to be a real bug after all because of the way the program asks for the default compressor which seems to be not supported in wine, I'm investigating.

Also CamStudio 2.7 seems to have a problem and does not open the Video Options window (need to test in Windows).
