sorry about posting this hear but i would be interested in peoples views on this in light of my set up.
i have a very old PC which through ps3media does not stream even 720p properly let alone 1080p. I was a happy user of mkv2vob and once transcoded it would quite happily stream 720p films etc. however i also sometimes copy the file to the ps3 as well (the only option i have with ps3media due to my pc's crap performance).
therefore purely on the basis of quality is there any differnce between a copied ps3media file or one which has gone through the mkv2vob process
