Finding a decent movie of choice in Blu-ray may still be a problem, but that hasn't stopped Sony from thinking big. It recently demonstrated a 400-Blu-ray disc changer (doubling last year's 200 disc endeavor) at CEDIA. The upped version features a slimmer avatar and is still a demo piece. The BD Mega Changer features latest Blu-ray standard, BD-Live, which means it can hook up to the Internet and download additional content. The unit will also pack an RS-232 serial port for custom installers. The good news is that the player also reads CDs and DVDs, so conjuring up that collection won't be a problem!
