....regarding the lack of sound in some stations, they once told me to switch/interchange the red and white cables. Pluck the red cable and insert where the white should be on the decorder only and vice versa. Regarding the channels dissapearing, search them again and then go back to the search screen and just below you will see some thing listed below labelled "new channels" then change the word "automatic" appearing on the right side of it to "dont remind me ......or something like that". The stations wont go off again. All in all, the channels have very poor quality sound, unaweka volume yote ya decorder na ya tv to at least hear something. Bure kabisa. In addition, the movies shown on showtime are repeated daily so what you watch today you will watch on thursday, etc. I regret, only that it was free.
