In between i have found some additional information about the PMT Type for AC-3 streams from http://www.coolstf.com/tsreader/support.html: > What's are the "Defacto" and "ETSI" radio buttons on the record dialog for? > > As usual, this MPEG-2 oddity can be blamed on General Instrument which is > now part of Motorola. When the MPEG-2 specification was written there was > only support for MPEG-1 or MPEG-2 audio. General Instrument wanted to use > Dolby AC3 for their audio coding but had no way to tell the receiver that a > PID contained AC3 audio because MPEG-2 didn't allocate a PMT type field for > AC3 - just for MPEG audio. So General Instrument used one of the user > defined PMT types of 0x81 for AC3 and this has now become the standard in > North America - it's used on ATSC terrestrial transmissions, Dish Network's > Direct-To-Home satellite service in addition to the Digicipher II system > from Motorola.

On the > input side, when TSReader looks at a stream it can handle either "Defacto" > or "ETSI" ways of doing non-MPEG audio. The following table lists the > additional audio formats supported by TSReader: > PMT Type Descriptors Resulting Audio > 0x06 AC-3 descriptor AC3 > 0x06 BSSD descriptor LPCM > 0x06 DTS1/DTS2/DTS3 descriptor DTS > 0x81 None AC3 > 0x83 None LPCM > 0x85 None DTS So i think dvbcut should also support this defacto standard types (0x81,0x83,0x85) for audio streams.
