Does such a comparison exist? I've gone through a lot of this site without finding one. I apologize if I missed it. Not looking to delve into all the technical details, just want to know the capabilities of each system, assuming a 4 room set up, particularly along the lines of how multiple people can use each one independently, like: 1. How many people can independently watch, pause, and rewind live tv with each setup? 2. How many channels can be watched/recorded at the same time (similar to question 1) indendently by people in different rooms? 3. Are all the above in HD, or does it drop to SD after a certain number of tuners are used? I've also tried Directv live customer chat, they say I can do what I want but refuse to tell me how many tuners are available which makes me suspicious. I'm currently a DISH customer evaluating Joey upgrade vs. Dish whole house DVR. Direct has the edge on cost since they'll do it free and DISH wants existing customers to pay for the upgrade, but need to verify all the capabilities I need will be there with Direct. Thank you!
