I was wondering when and if HD CH Channel 521 on Rogers will finally be telecast in 5.1 DTS? I have noticed that most of their programming fills up the screen in HD on an HD capatible flat screen TV. The other problem is when they broadcast the same program that a U.S. Channel is carrying which is usually in 5.1 HD then it reverts back to audio on 2 front speakers and a subwoofer only. Could someone please answer this. Thanks in advance.
