I use a Tablo DVR, and the “Tablo Channel” with a ROKU Ultra. Most of the time, when fast forwarding or reversing, there is a “streaming” view, showing a stream of images as well as a time bar below the images. However, occasionally the fast forward/reverse view is just a static image and the moving time bar! I want to know why this happens, and “where” it happens. Is it a ROKU issue, a Tablo channel issue, or recording issue. It can occur when the same program is recorded, from the same channel but at different times.
