When I went to my parents at xmas, I copied some files from the playmedialist onto the portable hdd to take and watch whilst there (we both have HDR-T2s). None of the files played on the other machine ('scrambled or not available' message). I did notice that one of the files was HD, so may not have played (should be decrypted though), but the others? I'm sure this should have worked? notes: they did work on my machine when we got home and i tested it. i can't remember how I copied the files: I think it was simply via the media browser... but I do recollect that I could have used the custom software to do a move or copy/paste - in which case this thread could be in the other forum.
