Last month I replaced 2 old RCA SD receivers at the house/shop building and the shop antenna setup was an 18" Round. That went well and we wanted to Ultimately convert to HD Receivers in the house and change the antenna setup to a SWM Slimline 5. So I went shopping (and DTV Access Card Dept Verfying) on Fleabay buying a HR24-700, a Virgin H25-700, and a H25-500 receivers, a Slimline 5 antenna setup, 2 access cards from DTV. Had it all installed yesterday and for the most part everything went well with just a couple of problems or in all likelyhood, I just don't quite know how to operate/setup/use these newer receivers. So a little insight from you experts would be appreciated: 1. The H25-500, On ONLY 2 Channels, FOXNews 360 & DIY 320 I get the 771 msg. All other channels are AOK and come in fine when chosen. I have red button reset 3 times, and hard reset/boot 2 times by unplugging the power cord. No Luck, same result. Other than that problem, works great. 2. The HR24-700, really like it, and since this is my 1st DVR experience, I tried recording and much to my pleasent surprise, worked great. But I do not seem to be able to get the AutoTune Function to work on it like the other receivers. Is the Autotune function on DVR's different than straight receivers? 3. Went out to the shop to putter around and tune on one of the new D-12 SD setups and get a 726 msg. Called DTV who's only advise was to reset/reboot which by the way did not solve the problem. I suspect a screwup on DTV's end. 4. Can a D-12 be setup/programmed with an RF capable remote? Only one more Old SD Receiver to replace (Samsung 303W) in the motorhome and the DTV verified HR20-700 is in transit as I type. HR20's are the last HD receivers with an external OTA Antenna coxial port and are relatively easy to setup as SD antenna connection (my MH King-Dome 9702). I live right across the Strait of Juan DeFuca from Victoria/Vancouver BC and like watching Canuckistan OTA TV. Any other helpful hints or advise??
