Hopefully this week we'll be getting the HR44. We plan to keep our 2 HR21-100/700. We'll also be getting a new HDTV (either Samsung or LG/non-smart tv). The new HDTV will be running one of the HR21's. I also plan to use the wired CCK. Is there a particular type or brand of HDMI cable that works best? Where to purchase? (This would be for the new HDTV) In using the wired CCK, will I be able to access the TV's manufacturer website to do a firmware update if necessary? Thanks!
