Dave, when I started using the NEWSTRUCT drivers I lost the ability to
get information from dvbtune -i.  I was so concerned I started writing a
utility (as yet unfinished) to dump the SI.

The only way I could get the new SI for the recent changes in the UK was
to run the OLDSTRUCT drivers with dvbtune.

I get bizarre output from dvbtune -i at the moment.
It either fails to read anything or gets bad info.

Is anyone else seeing this?

Where I am - 641833333 is the BBC MUX with BBC1,2,3,N24 on it - all this SI is
for channels on 842000000.  Just to be sure there was no problem with dvbtune
NOT tuning - I had been watching N24 via dvbstream prior to capturing this.
