Unsynced TS or PES is useless, because decoding will be completly gaga. On sections -nocrc is default, because there might be private sections (e.g. ECM) or DSM-CC sections with no or different CRC calculations (e.g. dsm-cc datagram). Software packet sync is default as if 1.4.10 and cannot be switched off.
