Ask TBS for this
Need only redesign driver BlindScan support like implemented in my StreamReader (single-step scanning). And this open way for DVB-soft developers for implementation hardware BlindScan (for example TransEdit now support brute-force software BlindScan).
ProgDVB engine have most advanced device modules architecture, so possible flexible extend interface. But another soft have monolitic architecture (like DVBViewer, TransEdit) or simple device modules like DVBDream, SmartDVB. So BlindScan support implementation depend from soft vendors and device drivers vendors (50%/50%)
