Blu-Ray Drives

[Wes Morgan]

I just "upgraded" from a DVD-RW drive to a blu-ray. The weird thing is, I 
can access the BD discs just fine (encrypted obviously), but the damn 
thing won't let me access DVDs:

My own DVDs that rip fine with my old drive now simply won't even play 
back. Obviously this must be related to CSS, but I've never seen it deny 
access to a disc. Anyone know what gives? Is there something different 
about how these drives handle DVDs?
