NVIDIA's new driver that is currently in beta, 195.39, does not work for MPEG-2 files with Badaboom. These drivers are for Windows 7-64 bit and Windows Vista-64 bit. The only files that this should affect are MPEG-2 files. We are looking into a fix and will post updates as soon as they're available.
195 Driver Update
So while the 195.39 BETA driver from NVIDIA does not support MPEG-2 files for Badaboom, it looks like this will be fixed official release of this driver.
