It cannot be said Microstudio will not play .WAV files. It WILL play a .WAV file directly from the cdr/cdrw drive. You get the audio and a black screen.

This is kinda far out, but you can also import a .WAV file through Microstudio as a CDG and get exactly the same results, play the audio with blank screen. In that manner Microstudio can be fooled into playing a .WAV from the hard drive.

Sounds like a non compliant burner issue, but agreed a lot more info is needed.
