I have WAV files from a Casio Exilim digicam that aren't readable by Pinnacle Studio 9 because they are not PCM codec'd. I converted them with Switch, and began importing clips into my video project. Studio crashed after two clips were added and now Switch tells me it can't convert the original WAV files. I have downloaded the WAV files again from the digicam but Switch won't touch them. Do I need a plug-in, a driver, or what? Mort
