I can't get DVDA to reliably play any type of audio file as a preview. It will play one sporadically, with no noticeable pattern. Vegas previews correctly now that I switched to the ASIO driver for my RME HDSP card, but DVDA doesn't offer that option. So far, tech support hasn't gotten beyond the usual "check your control pannel settings" phase in trying to solve the problem. Anyone else run into this?
