hi guys! i hope you all had a great weekend! i have heard alot of talk about 4dtv. i have a analog and dvb receiver and am curious about the 4dtv system. what are the advantages of a 4dtv other than the ala carte packaging? since i already get feeds from analog and dvb and have a dish network package what do i benefit from by getting a 4dtv? there are not many feeds in that format. right? thanks guys
