Something like this happens in Spain. DVB-T channels are updated by vdr
with an extra milliard (the thre 0s).
Actually I see two copies of each channel. The right one with which I
populate channels.conf to start with and another copy added by vdr with
the three extra 0s.
In addition, vdr sometimes updates fully operational channels to wrong
values, which results in a blank screen.

All is solved disabling the 'Update channels' option, though.
