| 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. |
