TTUSB_HWSECTIONS:
the DSP supports filtering in hardware, however, since the "muxstream"
is a bit braindead (no matching channel masks or no matching filter mask),
we won't support this - yet. it doesn't event support negative filters,
so the best way is maybe to keep TTUSB_HWSECTIONS undef'd and just
parse TS data. USB bandwidth will be a problem when having large
datastreams, especially for dvb-net, but hey, that's not my problem.
TTUSB_DISEQC, TTUSB_TONE:
let the STC do the diseqc/tone stuff. this isn't supported at least with
my TTUSB, so let it undef'd unless you want to implement another
frontend. never tested.
DEBUG:
define it to > 3 for really hardcore debugging. you probably don't want
this unless the device doesn't load at all. > 2 for bandwidth statistics.
