	These days I am giving a try to vdr to consider switching from
MythTV, and I found this problem too.  I also saw that tzap + cat dvr0
worked fine, so I did a little debugging to check the differences in the
DVB frontend configuration.

	And the only different field was the inversion parameter.  For
whatever reason, the NOVA-T USB2 doesn't works with inversion off (I0),
which is supposed to be always so in DVB-T.  The same happens with tzap if
you use INVERSION_OFF, the multiplex can't even get locked.

	So, to make it work, use inversion auto (I999, or just don't add
the I parameter).  In the vdr wiki it says "please do NOT use 999", but I
don't know who wrote it and why.  Does anybody know the reason for this?

Unha aperta,
