I've to capture my radio channels via satelite because my pc has no internet connection. Although my TV-functionality is okay, I'm still very far from a good WAF for my radio function in MP;-)

When I enter in "My Radio" MP need a long time to connect the radio channel (audio signal), some times there is even no signal. If there is an audio signal and I want to change the radio channel, I have to wait up to more than 30 sec to tune the new channel.

Is there any specialist who can give me some help to resolve my problem

Best regards
