Yes DVDAE is DVDA Explorer.
DVD Audio Extractor is the newer one.
I have ended up using DVD A E just for convenience. I think DVDA E stopped development a few years ago now and there ended up being something added to the DVDA format later on that it couldn't read.
Between DVD A E and MakeMKV, everything is pretty convenient now. Really, the only ringer is decoding the DTS2496 format. I ended up grabbing the codec from this Arcsoft product that was bundled with something else for a short time a few years ago. They wanted you to buy some $1200 media player suite or some such. I wasn't playing along. The thing it was bundled with was only written for Windows, so I have this kludged mess of a combination of this other Windows app AudioMuxer with the Arcsoft codec hacked in that I run in OSX with Wine.
I think the media player suite apps are down to around $400 these days but I'm still not playing. I still use the free app Songbird. I like that you can just set Core Audio to 5.1 and forget it. Mix and match formats in a playlist (5.1, 4.1, 4.0, 2.0, etc) and everything comes out the correct speakers.
I'm conformable enough with the decodes to buy the discs that come along. The Tull DVDs have been released in this awful format and I decided I can't live without hearing those Steve Wilson 5.1 remixes.
I gotta say though, it's getting harder to find things to complain about with all the HD music releases (and at least a few of them surround) these days. If someone would have told me a few years ago that the Yes and Tull catalogs were going to be remixed in 5.1 and further they were going to be done right - truly right - I would have laughed in their face. Like, that wasn't allowed to happen in the alternate universe where Jimi Hendrix is still with us.
Someone has to go out of their way being greedy now... as we've been discussing in the thread. :)
PS. Sorry about the tech corner digressions. If someone is getting upset, just let me know.
MOD EDIT: Please take the tech discussion to the other thread and leave this for the Early Years release.
