This may have been asked before. If so, I apologize. But, the various threads are very confusing. I do not want access via the internet, or cellphone or anything like that. I am a DTV subscriber since 1996 and have bought and installed all equipment and upgrades myself. Currently I have: !. A 5 LNB Slimline Dish 2. A SWM-8 switch with 2, 1x4 splitters. 3 1, H20-100 4. 1, H21-200 5. 2, HR22-100 Several legacy Receivers. All installed by me and working perfectly. Question: If I buy 3, DECA MR-01 units on eBay (for the 2, Hr22 and 1, H21), is that all I need to share recorded programs between the 3 units? No DTV installer required? No router connection? No internet connection? No $ 3.00 fee and calls to CSR's? I certainly hope so. If not, what else do I have to do?
