Just put the video in there and try to play to check. If the videos use an audio codec that foobar can play, it will playback the audio. Same thing can be said with Winamp. I do have vgmstream installed, so that probably helps some.
Actually, is bvs even an audio/video format? How large is the file? From what I can tell from just some very light research, it doesn't capture any audio/video, just gameplay data like cpu commands/player inputs and the like and plays that back in the emulator.
