I've recently downloaded OCP's six-disc set (the Classic Editions of the OT, Deleted Magic, Return of the Ewok, and Special Edition Hype) and will be watching them on my computer until I decide to get off my ass and buy some DVD-Rs. For some reason, the menus for the three "Special Features" disks are silent, and if I play more than one part during a sitting (like watching the main film, then playing a special feature), the film itself is silent. My default player is Media Player Classic, but the same thing happens with Windows Media Player. Any idea how to fix this?
