This was happening because, in the previous coding, the bandwidth calculus were after the check for delivery system changes. The previous patch changed the logic to estimate the bandwidth to happend together with the changes at the delivery system. So, with a one-statement change, it is possible to make the tuner to reconfigure, in order to adjust to bandwidth changes. this will likely fix issues on countries that use 7MHz/8MHz DVB-T channels.
