I have had a couple of DCT6416 160GB HD cable boxes for quite some time. The only advantages that I can see on the surface of going to DCX-series PVR or the new ARRIS portal/gateway system is:
1) larger recording capacity (500GB, 1TB), 2) menus look nicer, and Galaxy music has the snazzy cover art, and 3) record to one source and access from multiple TV's if using the ARRIS system.
Do any of these newer boxes offer anything in terms of access to content or quality of viewing that is not available to my older DCT6416 besides larger and more convenient storage ? Thanks for the insight.
