Havent visted this site or posted for quite some time....I got a new TV for the bedroom yesterday, so I now finally need to upgrade my SD TiVo box (don't even know the model, it's about 7-8 yrs old) to an HDDVR....I currently have 2 HR20's and have them hard wired into my router with Whole Home active, with a SWM8. I'm thinking about going with the HR34 instead of a HR2x, and adding it to my network. Just to confirm, this will allow me access to all 9 tuners/3 playlists from all 3 TVs, and all that will need to be done to accomplish this is upgrade my SWM to a SWM16, correct? Also, what is the difference between "supported" and non-supported MVR... Thanks!
