For those of you that want both worlds consisting of DNS and Locals don't forget the AM21. An AM21 will tune OTA digital broadcasts and allow the newer receivers since 2007 or so to record the programming. Of course you will need a suitable antenna to capture the signal. This combo allows you to tune true uncompressed OTA HDTV anywhere you have signal. DirecTV Locals are compressed and some quality is lost in the process. Most notable watching outdoor sporting events. An AM21 allows you local broadcasts at home and where you are parked so long as you have signal.
Also, if you qualify for DNS, DirecTV will still provide you their Locals at the "Service Address" on your bill. They are are part of your package and you cannot ditch them and get a credit. Must be another FCC rule to prop up local TV stations. Mine were on the 119 and I just use an SL3 LNB and can'tget them even if I was under them. If you go with a Trav'ler SK-SWM and your Locals are under the 119, you can't get them either. But, you will pay for them.
