I've just fixed the issues on the TODO list. The DVB v5 code is now working fine
for ISDB-T.

Pending stuff (patches are welcome):
	- Implement v5 calls for other video standards;
	- Remove the duplicated DVBv5 code on /util/scan/scan.c (the code for calling
DVBv5 is now at /lib/libdvbapi/v5api.c);
	- Test/use the functions to retrieve values via DVBv5 API. The function is
already there, but I haven't tested.

With the DVBv5 API implementation, zap is now working properly with ISDB-T.
gnutv also works (although some outputs - like decoder - may need some changes, in
order to work with mpeg4/AAC video/audio codecs).

Have fun!

Cheers,
Mauro.
