What windows update was this exactly? It's possible that the Universal Serial Bus controller drivers got updated and aren't working well. I'd go through your USB devices and your BD driver and see in device manager if the "roll back driver" button is available on any of those things and try that first.So I've been using a Pioneer external BD player for months now and it's work fine, both playing and ripping discs. No issues. But then last week, after a Windows update, it wouldn't read at anything above 0.3x speed. Playback is choppy as hell and ripping is at a crawl at 0.0x at times. I figured the drive had crapped out, so I bought a ASUS BW-16D1X, but I'm getting the same problems. My USB ports are fine. Drivers updated. Firmware updated on both BD drives. DVD's read rates are fine. Any ideas?
