Why not simply turn off updating channels in VDR's setup? ;-)

Of course, finding out what actually causes the trouble would be
a good idea.

If you align the two channel definitions...

BBC ONE:489833:I999B8C34D34M16  T2G32Y0:T:27500:600:601,602:0:0:4163:0:0:0
BBC ONE:489833:      C34D34M16B8T2G32Y0:T:27500:600:601,602:0:0:4163:0:0:0

...you can see that the _only_ difference is that the first one has an additional
I999, which means "INVERSION_AUTO", which also happens to be the default.
And since the second definition doesn't contain I999, the default will
just be the same, so I can't really see why these two lines would behave
any different... (the sequence of the B8 parameters doesn't matter).
