channels are going m8, its fine for a few minutes. there is another thread here getting the same problem. say i go to sly movies, then flick over to bbc1. they are there fine. after i try and go back to sly movies they are gone, black screen. the problem has been solved by reflashing umpteen times however i had problems like this when i used to play with the 500c. all u did to clear it up wash refresh your channel list from the blue button. hence why i was asking if there was a channel refresh button in the menus somwhere.
