PLEASE HELP! "Web Video HotList Frozen on Roamio" title says it all. I can get to the app interface, it looks modern and pretty, but once in there none of the RF remote buttons do a single thing, except for the TiVo button which kicks me right out of the app. (IR reception is obstructed) BACKGROUND INFO: This is a 2 week old (lowest end) Roamio with OTA only, using both Ethernet and WiFi. I have Lifetime service, new remote batteries, and a 3TB WD AVGP single HDD inside. All other TiVo functions and screens seem to work fine. I can even use the normal FIND (or my PC's web browser via TiVo.com) to download web content to Roamio, but the primary "Web Video HotList" app seems to not respond to any controls.
