I have a series 4 TiVo and a TiVo Stream device that I use to download shows onto my iPad 2. The problem I'm having is turning on the closed captioning on the shows downloaded to the iPad. The CC works on the DVR when I watch the shows on my TV, but the same show won't have CC on the iPad. The button to turn CC is available on screen, but simply won't do anything. Rebooting the TiVo, the Stream device, the iPad or uninstalling and reinstalling the TiVo app on the iPad has no effect. How do I fix this?
