I had a problem with playing back in progress OTA recordings and buffering live OTA tv. All 10 OTA channels and on both TV1 (IR) and TV2 (UHF). THe 2 sat tuners worked fine. I also noticed that the box was very sluggish and would randomly reboot while recording from OTA. When buffering SAT tv it would count the buffered time smoothly evey second, buffering time for OTA was updated every 2-3 seconds. Support took it as a software bug and reported it DISH engineering. Sorry, I dont have the SW versions my 722 was running handy. The next day the field service tech was out to repoint my 61.5 to 129. This was to pick up the new HD content that I discovered here (thanks). They asked if I had any other troubles and I mentioned the buffering problems. After I easily demonstrated the problem, he swapped me to a new 722k. I had already lost all my recording though the trouble shooting process with support the day before. The field techs dont carry the OTA tuner modules for 722ks, so I had to convince customer service to comp me one. Given the circumstance it wasnt too difficult. I have been VERY happy with the HD absolute package and price for 2 years, but now I am also Im very happy with online tech support, field support, and customer service! I love the new iphone app and the new tv everywhere (sling tech) looks really cool too! 2 years and counting of TV bliss.
