I'm showing three audio plug-ins in Vegas 3.0, Acid 3.0 and also under DirectX in SoundForge 5.0 that I wasn't previously aware of, and that cause programs to crash. They are: Audio Flt, rmbeep, and MGI Switcher. Anyone know where they would come from. I do have MGI VideoWave 3.0 on computer, preinstalled since I got it, but just never noticed these before. I suppose I could just delete them but haven't tried yet pending advice. Anyone heard of these? Do these come from Sonic Foundry?
