My new desktop will have a six or 8 core xeon rocket lake processor, at least 16GB of ECC RAM and a late model Plextor BD burner. My Oppo and Pioneer BD players won’t play ISO files and I wouldn’t want to use transcoding or anything which would degrade the BD’s lossless DTS or PCM sound track. So would the only solution be to then burn a one to one copy of the AnyDVD HD decrypted BD disc? That is, add an external BD burner to my rig to do the burning onto a BD-RE? If yes, is a 25GB BD-RE usually big enough to do a one to one dupe, or would I most likely need a 50GB BD-RE? Will Clone BD help me do all of this easily? What kind interface to use between the desktop pc and the external drive for fastest data transfer? Is USB 3.0 about the fastest available? If not, what to use that's compatible with most internal and external BD burners? Can someone recommend one or more external BD burners which offer the best balance between burning speed and error prevention? Thus, with the above computer hardware about how long would it take to burn the dupe of most full length BD movies?
