I am waiting for my new HR20 and have a question about the local channels that DirecTV feeds. I live near Boston & can get everything on an antenna, but I can also get locals from DirecTV. Will they feed me everything I can get OTA? Is the quality the same? (Compressed on satellite vs. OTA) DirecTV insisted that I don't need an antenna installed. (They're coming on 1/16) I'm not sure if they won't do it or if they just don't want to do it. Is there any advantage to receiving HD from an antenna in terms of quantity and / or quality?
Welcome to the forums! :welcome_s
D* will not feed everything you get OTA at least now. You will likely miss PBS and all the subchannels.
Mileage as to PQ varies. Initially at least, MPEG4 via satellite was not as good as OTA here. Other have reported they can't tell a difference and others have reported major improvements by the satellite delivered PQ. We know that Directv is also improving their uplink facilities including new software for the MPEG2 to MPEG4 transcoders.
You will also find that a good OTA is rather weather proof. Wet snow on the dish will cause sat. delivery problems that won't happen with OTA.
And lastly, OTA takes more disk space. On some shows, the difference between OTA and sat. HD won't matter, but space might. Sports shows, which also eat up the most bandwidth, tend to expose the PQ problems.
So, now that I've made this clear as molasses in January, I hope you have some information to make a decision.
