Heh, I really don't want 3 copies of a lot of them
so I won't rebuy them.
After you mentioned what Paramount was doing, I checked hidefdigest but they usually gave the same audio marks on Paramount titles even when the bitrate was lower (basically saying they weren't happy Paramount was doing that but they didn't really notice a difference -- the Babel review, for example). To tell you the truth though, it wasn't something I even thought about checking when purchasing them.
BTW, some Paramount titles offer DTS at 1.5mbps (like Aeon Flux, for example). Shouldn't that be just as good?
