Why they chose to add V.AUX instead of PC is beyond my understanding..All BeoVisions nowadays can act as PC monitors, so the PC key makes more sense to me, besides, the BeoMaster 5 owners will have to reprogram their product to make it react to V.AUX rather than PC commands, when used in a video setup..
Finally, as others said, "TV" and "DTV" could have merged into a single source (it was working like this on BeoCenter 1), since old analog TV is gone, but the term "TV" remains universal, in any language: ask a French or a German what "DTV" means, they don't know, ask them what "TV" means, they all know !
