After the debacle of the Hr20 locking up after over a year and them sending me a new hr21. I asked if since my 20 was still fine since it was a software issue and I need my OTA if I could keep the 21. They said they will waive the sale cost and just do the extra receiver for the 5 bucks a month. Problem is they only sent receiver with remote. I already use my 2 filters on my Hr20 and now want to disconect one of my 15's and in place put the new hr21. But I have to set it as OVAL 3 LNB's to work since I dont have the 2 filters. YIKES! Dont want to push my luck by asking Direct for some.
