@tebasuna51 well... i got a very nice setup (high-end) right now that i am very happy with and i would like the best sound possible with my setup... i have non to little knowledge about downmix and flac vs. m4a but it does not sound right that a aac would be a good replacement for flac? and if we would just talk about harddrive space it is not interesting to save space i prefer good sound over high compression. is there a better lossless way to downmix?

@Inspector.Gadget my bad i found some info about this after that i posted here.
@tebasuna51 well.. i got a 2.0 amp and there is no mixdown and even if there wore there would not be enough bandwidth with a optical cable. so the processing most happen in the computer. learning how to downmix is among other things just for learning and testing to see how much cpu/mem the ffdshow mixdown requires. |

correct me if i'm wrong: -when eac3to decodes .dtshd to .lpcm it remaps the channels from correct wav order output by arcsoft decoder to blu ray order because the resultant .lpcm file is supposed to be used for blu ray authoring. -when eac3to decodes .dtshd to .wav it does not remap the channels because the resultant .wav file is not supposed to be used for blu ray authoring but should be used as lossless source for further encoding to ac3, aac, etc. now, if above is true, i have the following problem: i cannot import the .lpcm output of eac3to into multiavchd (it shows no tracks imported after clicking on such file), and if i use the same .lpcm after fixing it with pcm2tsmu multiavchd for some reason detects it as aac(!). only importing in .wav container works fine. so is there a switch to get eac3to to output .wav with blu ray style channel order suitable for importing into a blu ray compilation? |

when importing .wav to bluray it will be muxed as .lpcm (.lpcm is a type of .pcm...)
if the .wav is bigger than 4gb (in 99% of the cases) then decode to .w64... _

Another issue
eac3to does not identify .dts streams
(read: .cpt / .dca padded-with-zeroes for "SPDIFing") if the bitrate is different than 754 / 1509 kbps and/or the channel count is less than 5.1. Example: -- create a stereo .cpt @ 384kbps -- use spdifer.exe for generating a "little-endian.raw" -- use swab.exe for generating a "big-endian.raw" MediaInfo (0.7.23BETA) recognizes only the little-endian file as DTS, and mkvmerge (3.2.0) recognizes both the big-endian and the little-endian files as DTS, — whereas eac3to fails in both cases. <REMINDER> Code:
Valid bitrates and sampling frequencies for "Coherent Acoustics" compression: Bitrates (kbps) : 32 56 64 96 112 128 192 224 256 320 384 448 512 576 640 754 960 1024 1152 1234 1280 1344 1408 1411.2 1472 1509 1920 2048 3072 3840 Frequencies (kHz) : 8 11.025 12 16 22.050 24 32 44.1 48 Last edited by Midzuki; 29th April 2010 at 03:28. |

Newbie question (and probably already answered somewhere that I can't find): On a few AnyDVD Blu-ray rips, when I try to analyze the structure, I sometimes get the message "HD DVD / Blu-Ray disc structure not found" reported by Eac3to v3.18. When I examine the structure it looks absolutely fine to me, so I don't know why Eac3to is balking at it. What tests does Eac3to run to determine proper structure? How can I "convince" Eac3to that the structure is valid? Any other ideas or suggestions?

Master directory created by AnyDVD is "E:\BDROM". Under that I have 2 directories - "BDMV" and "CERTIFICATE". 1. Under BDMV I have several directories: AUXDATA BACKUP BDJO CLIPINF JAR META PLAYLIST STREAM and 2 files: index.bdmv MovieObject.bdmv The directories "AUXDATA", "BDJO", "JAR", and "META" are all empty. The directory "BACKUP" seems to have backups of other parts of the disc. "CLIPINF" has 15 files sequentially numbered "00000.clpi" to "00014.clpi". "PLAYLIST" has 14 files numbered sequentially from "00000.mpls" to "00013.mpls". "STREAM" has 15 files numbered sequentially from "00000.m2ts" to "00014.m2ts". 2. Under CERTIFICATE I have one directory ("BACKUP") and one file ("id.bdmv"). Under that directory I have what appears to be an identical copy of "id.bdmv". From what I know this structure looks sound to me, but apparently there is some test that Eac3to is using to determine if a valid Blu-ray structure is found and this particular rip does not pass that test. I have done literally hundreds of Blu-ray rips and this is now the 4th time I have run into this error message from Eac3to, and all 4 of the rips looked perfectly good to me. I have tried PM'ing madshi over at AVS, but I guess he hasn't been around lately or is too busy or just not interested (not that I blame him... ). I would appreciate anyone who could help explain why Eac3to is balking at certain rips and what I can do to "convince" the program to accept the structure. |

@oddwunn
1) Have you tried playing this BluRay "package" from your hard drive (AS a BluRay, NOT as individual .M2TS files)? Does it play properly? 2) I do not use AnyDVDHD, but I recall seeing that it creates another folder named (IIRC) "Sly!", that contains the remnants of the original "AACS" folder/directory. 3) What is the title and region of this particular original, commercial BluRay disc? |

I recently reinstalled my OS (and of course EAC3TO!!) and I am having some trouble. I have eac3to v3.18, Nero v7.9.6.0, and I also have the bluray/hd plugin installed. I keep getting the message:
Nero Audio Decoder (Nero 6 or older) doesn't seem to be installed http://www.nero.com/eng/store-blu-ray.html CAUTION: You need Nero 7. Nero 8 won't work with eac3to. I have all of that, any ideas why eac3to is not recognizing it? Also, using win7 x64. BUt that makes no difference as that is what I was using before and it all worked. Thanks |
