[quote="abestern"] Here's the last few lines of output of configure: Code: config.status: executing Makefile commands configure: OpenCL 32-bit development files not found, OpenCL won't be supported. configure: libgphoto2 32-bit development files not found, digital cameras won't be supported. configure: gstreamer-0.10 base plugins 32-bit development files not found, gstreamer support disabled configure: libmpg123 32-bit development files not found (or too old), mp3 codec won't be supported. You don't need OpenCL. If you're not using a digital camera, you don't need libgphoto2. If you want sound, you need gstreamer and libmpg123. > > Do I need the libmpg123 library to embed mpeg movies in powerpoint? Right now, it says that I am using an incompatible format which is an untruth. You need libmpg123 for mp3 sound. You can't embed mpeg movies in Powerpoint. http://bugs.winehq.org/show_bug.cgi?id=16485 You can embed avi files, but you need to install Windows Media Player to the same wineprefix. Follow the instructions in the AppDB. http://appdb.winehq.org/objectManager.php?sClass=version&iId=12813
