Assigning to Ludek to review what can we do about it using the current burning engine. However, probably not very high priority, it doesn't seem to be used too often. |

There doesn't seem to be any DVD-A specification on the web as stated also here: http://dvd.wwwdotorg.org/specs/specs.html Nevertheless it is about proper filling of AUDIO_TS directory on the DVD that must contain appropriate data in order to create DVD-A. I burnt a DVD-A using the other software and structure is: VIDEO_TS - directory that is empty for DVD-A AUDIO_TS - directory that contains following files: Ats_01_0.ifo - encrypted info file (where a certain audio or subtitle stream is located, etc) Ats_01_0.bup - just backup copy of the Ats_01_0.ifo Ats_01_1.aob - actual audio data stored in LPCM format or losslessly compressed with Meridian Lossless Packing Audio_pp.ifo Audio_ts.bup Audio_ts.ifo Primo doesn't allow a functions for creating IFO and AOB files so we need to create them by using another tool (e.g. http://dvd-audio.sourceforge.net/ ) or ourselves. IFO is encrypted, some source codes for IFO parsing are available here: http://forum.doom9.org/showthread.php?t=50552&highlight=ifo and for IFO and AOB creating http://dvd-audio.sourceforge.net/ Some useful links: http://www.doom9.org/index.html?/dvd-structure.htm http://en.wikipedia.org/wiki/DVD-Audio |

Note that DVD-A doesn't seem to be commonly used and also many DVD ripping tools don't support ripping of DVD-A although they support DVD-V (e.g. DVD Audio Ripper Deluxe). |

There seems to be also some other alternate formats like "Audio DVD" which isn't DVD-Audio, but a different format that can be created e.g. by Audio DVD Creator ( http://www.audio-dvd-creator.com/ ). The main difference is that "Audio DVD" writes all data to VIDEO_TS directory in order to be compatible with all DVD players unlike "DVD-Audio" that writes the data to AUDIO_TS directory and thus many DVD Players cannot read it. 'DVD-A' will only play on DVD players displaying the DVD-Audio logo. They are not compatible with Video-only players. 'Audio DVD' does play on Video-only players. |

Moved useful info from 0002785: The Unofficial DVD-Audio Specification: http://dvd-audio.sourceforge.net/spec/aob.shtml [^] An open-source project for DVD-Audio authoring: http://dvd-audio.sourceforge.net/ |

Changing priority to normal, it seems that 'DVD-A' and 'Audio DVD' are used rarely. There are articles on the internet saying that DVD-A and SACD are dead. Also on our wishlist forum isn't any request for DVD-A support. There are more useful features for MM 4.0 to add. |
