Hello everybody, my language is not english so I hope to make you understand....Here is my problem: I installed the frre Progdvb and everything seems to work correctly but when I look to the Tv ( I have an USB receiver...) on the bottom of the screen there is a bar loading (maybe registering I suppose) and when the bar comes to the end (3 minutes, more or less I think) of the space everything stops so I can't watch the TV for more than 3 minutes. How can I give out this limit?

Thanks in advance and if anything is hard to understand please tell me and I'll try to use different words.
