OK, I have one HR20-700, one H20-100 and new HR23-700. I'm about to trade-in the HR20 & H20 for two more HR23-700s....making three HR23-700s. I've enabled MRV Beta over my 10/100 network and kinda cool....however, the real desire would be to be able to set recordings to other boxes once you try to set on one box and have exceeded concurrent recording limits. I know this feature is not there yet but I think will hopefully be since the HD only (non DVR) settops allow this in MRV. Anyway, my setup is that I have all my settops in single rack down in my Home Theater. The outputs (Component Video) of these settops go into a very highend Matrix switch which drive all TVs and PJs in the house. So, in any room I can switch to any unit in the rack (eg. any HR2x or DVD player, BR Player, etc.) So, I kinda have MVR from a physical sense in that I can select any source from any TV/PJ. However, I want to enable DirecTV's MVR because of unified Playlist, remote maintance and as explained above hopefully they will implement remote recording sessions from one HR2x to another over MVR. Anyway, while my 10/100 works now I wanted to investigate DECA. Ironically since my settops (3 -> HR23s) all are in one rack together running RG6 from one to the other is super simple. I have Slimline dish with four RG6 inputs running to my Zinwell 6x8 multi with 6 RG6 outputs to the HR23s. Each HR23 is hook via RJ45 to a uPNP 10/100 Linksys Switch out DSL. So, to be "supported" I was thinking of implementing DECA. Question is with above setup...how ?...I think simple ? 1) Do I run RG6 from one HR23 to another, How ?...I mean what connection ? 2) Sounds like some adapter needed ?...from RJ45 to DECA ? 3) Some adapter needed to get on 10/100 ? Let me know thoughts....I would think with my setup/proximity of HR23s and right near my Linksys switch this would be fairly easy. Thx.
