I have come a long way in understanding how to back-up my Blu-Ray discs. At first I used DVD FAB PLATINUM but have pretty much changed rightover to AnyDVD and then TSremux to a TS file which you can do anything you want with. Still though, I am faced with some titles where there is no immediately obvious m2ts stream to choose. In most cases, MP2 or VC-1, there is just one key m2ts file of perhaps 15GB+, in others two of perhaps 10-12GB. Some though have a number of files of one or two GB in size. In one case I have all I need but out of three audio streams, DTS and DD, all I can get is the director's commentary. I understood that PGC.NET might help but it only works with DVDs. Any help or ideas?
