And for each DirecTV channel being broadcast in Dolby Digital, is it being broadcast in Dolby Digital 2.0 or Dolby Digital 5.1?
Another question, how expensive is a DirecTV STB that has Dolby Digital decoding? Can you mix and match Sony and RCA STBs and dishes? Compatibility isn't a problem? I currently have a bare bones RCA STB but would like to upgrade to a Dolby Digital STB. If anyone has recommendations of RCA or Sony models can you please let me know model #s, approximate cost and who may carry them for a reasonable cost (e.g., online retailers)?
Last question, do any of the Dolby Digital DirecTV STBs have integration of the OTA antenna (roof antenna) with DSS? My current RCA STB only passes through the roof antenna channels; it doesn't integrate it with the onscreen guide which would be desirable.
