slingbox switching itself off during zapping- please help

[slinggermany 3]

Hello guys,

I´ve rented a slingbox in the USA and use it in Germany. The picture quality is brilliant. The only problem is that after changing channels 5 or more times in a row I would receive a black screen. Then I can reconnect and continue watching. Does anyone know how to fix the issue permanently?

Thanks,

Martin
