[mythtv-users] two tuner and changing channels

[come se fosse antani]

Hi.
I have a Mythbox with two tuners: an analogical one (saa7134) and a
dvb-t usb stick (yakumo).
The first 3 channels are from the analogical and from 4-10 from the
dvb. At 11th channel again with analogical antenna.

If I'm watching 3rd channel and I push UP on the remote, myth show me
the 1st channel instead of the 4th.
How can I browse using numerical order instead of giving priority to
the input source?

thanks
