As we've seen with Discovery's Planet Green, and -- to a lesser extent, History HD, Food HD and SPEED HD -- these high-def channels prefer to change up (or shorten, at least) their names every now and then. The latest to take on a new identity is MTV Networks' MHD, which is apparently being redubbed Palladia HD in DISH Network / TWC's EPG. We've all ideas the name change will filter down to all carriers in short order, but we're just letting you know to not get overly excited upon seeing it emerge in your channel lineup. Sadly, you actually haven't gained another channel -- it's just that the one with the loudest commercials has been renamed.
