I have two TiVos, one Series 3 with two singlestream cablecards and one HD multi-stream cablecard. About eight months ago, I installed two Switched Video boxes, one on each TiVo, in order to access switched video provided by my cable provider, Cablevision. The switched video boxes blink green when they are trying to establish connection and solid when they have authorization. Originally, they blinked for 30 minutes when I was activating them and remained solid for months. In the last few weeks, they've alternated between blinking green and solid green for hours or even days at a time, indicating they are having serious problems maintaining authorization. The extra frustrating part is that when they successfully reactivate, they stop whatever the Tivo was recording. I've had two Cablevision repair techs over and both have realized that both of the boxes acting up at the same time means a systemic issue is at play. The most recent one, though, claims a TiVo software update is to blame that interferes with communication between the cable cards and the switched video boxes. Has there been any recent updates to TiVo software that would impact the performance of switched video boxes? Anyone have suggestions as to what I should tell the cable provider for what, to me, appears to be an issue with their network?
