+ 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.
