| Simplest and fastest way to compress LPCM audio to fit on DVD5 |

| 1) Import titles containing LPCM audio into TMPEG DVD Author including chapters.
2) Set audio compression method. Check if free space in compilation is larger then size of titles or VOBs without LPCM. 3) Move each imported video to a new title. 4) Output DVD video to folder without menus. 5) Replace original titles with new ones using VobBlanker. Agree when asked to confirm new streem settings. 6) You are done. In case the new compilation still does not fit on DVD5 compress it with DVDShrink. |

| LPCM cannot be compressed. It can be converted to AC3, which can be compressed. Is this 2nd step simply a conversion to AC3? |

| Shure, I just was so excited about the easy way compared to pain in old days and idea to spread the word I messed up the terminology.
I even did not bother to check if this is not common recomended practice. Excuse me! Sorry for my bad English. :) Apart of that I am not shure if conversion to AC3 is only "just" conversion. It also reduces the file size. It shrinks it. Actually it does compress. If not the LPCM itself then the audio for sure. |

| LPCM is uncompressed audio. AC3 is compressed audio, which is why it is (substantially) smaller than LPCM. So compressing the audio does a conversion to a compressed format (Mpeg-1 Layer-2, AC3 and DTS are all compressed to some degree). |

| There's a disadvantage in using TDA instead of Muxman: TDA can (and in most cases will) produce more cells (more than 1 per chapter) than input DVD video has. This needs more attention and extra steps (like splitting cells) at replacement in VOBBlanker. |

| Yes it is the case. But if it realy creates a problem one can change the order of titles and output project again in new folder then use the problematic title in a safe way. Tmpeg usually creates spare cells in the midle of the disk and not randomly around the project. So if there are many titles to remake, it is still easyer to mux and convert at one click of the button than to first export video, audio(s), subtitle(s) and chapters of each of many titles, then convert several audios, then mux all numerous titles again. It is difficult and time consuming task. |
