Last night I hit a mile stone. I figured out the viewsat sat file is junk and was missing ALOT of transponders, this was culprit in better than 95% of my troubles. I am finally, after a month able to watch pbs. Problem is there AC-3. I know this is something to do with home theather enc like dolby or something but my question is would a cheap suround sound system like those for 50 bux at wally world work? I want to save for a HD reciever before I get a surround sound!
