SATA DVD issues

[Edward Sanford Sutton, III]

For the encrypted DVDs, have you set a region for the drive to match? How are 
you accessing them? Further hardware information may help (people better at 
this than I) identify issues; what SATA controller connects the drive. Last I 
checked, my promise controller cards seem to have incomplete drivers for what 
is needed to support optical drives unless I misunderstood the code.
