I have just had a most amazing occurance--never seen anything like it in my professional IT experience.

THE LITE-ON 401S BD-ROM DRIVE HAS ACTUALLY PULVERISED A BD DISC.  YES, IT DISINTEGRATED THE DISC INTO ABOUT 100 PIECES. 

Ejecting the drive, I found a plastic nightmare of little fragments to dispose of.  Incredible! 

I have no idea why this happenned.  YET.

Whether related or not, the software involved was the latest Power-DVD version.  It occurred during a swtichover from HDMI to VGA output due to a display device change.

Don't know for sure yet if the Lite-On drive is toast, but I it probably is.  Have to consider which disc to test it with.  Yikes!

Was this a test routine of the ultimate in HDMI/corporate copy protection control?  Well, if it was, you lying corporate smucks, you got a bug--AS USUAL.  I wasn't even trying to cheat.  I was just switching to VGA output to get the damn thing to play in regular DVD resolution.
