_Can_ you play a blu-ray in a non-convoluted way?
Unless you're running Windows, I don't think there's a _straightforward_ way of playing a Blu-Ray on a USB drive. I'm pretty sure it involves some form of ripping, which is computationally expensive
If that isn't the case, please let me know, as I have a large collection of Blu-Ray disks, a USB Blu-Ray drive and a 2007 Santa Rosa MBP. (And as soon as my order comes in, a RMBP....)
