12310	VB 4.3 breaks encrypted DVD playing and image writing	ehagberg		"After upgrading to 4.3, I notice that I can no longer play encrypted DVDs in a VM (in this case windows xp) any longer, while downgrading back to 4.2.18 allows this to work again. I'm using passthrough mode.

Here are the errors I see in the host's messages logfile:

This problem/regression seems to break the ability to write DVD images in passthrough mode, which also works fine again if I revert to the previous 4.2.18 release.

However, the 4.2.18 release causes other issues (like the VM crashing at the end of certain programs that use the DVD drive)... so I hope this can be fixed in 4.3 where I don't have these crashes.

My host is running Fedora 19 with the 3.11.6-200.fc19.x86_64 kernel.
