Hi Mauro,

Thanks for the DVBv5 scan files. I had the attached draft patch sitting
in my tree. I don't think it is ready to be committed yet, but probably
worth sending now to discuss.

How do we want to manage the migration from DVBv3 to DVBv5:
1) point in time migration from DVBv3 to DVBv5?
2) maintain both until DVBv5 is in widespread use?

On a side note, I found a bug in dvb-format-convert; it cannot parse
DVB-T2 DVBv3 scan files.
