Try as I have here I can't seem find confirmation that Vegas Movie Studio or even Vegas Pro can import AND export DTS MA lossless audio.
Import and/or export support for only DTS HD lossy audio?
If no DTS MA support when might this change?
Nope. It is a proprietary format not licen$ed by Vegas.
What I'd want to do with several BD movies from my collection is that after the BD disc is decrypted I may want to perform one or more simple deletions of extreme violence and/or attenuate loud noises. But if the BD movie had a DTS MA soundtrack could Vegas at least import and decode it as a lossless 24 bit 48kHz or better 5.1 PCM soundtrack, so that I could then save all the changes and burn it all onto a BD-R or BD-RE disc? Hopefully, as the burned disc will then be free of the BD-J imposed copy protection will I be free to use a standalone BD player's features that were disabled by the copy protection like zoom, along with having surround and/or stereo lossless audio. Yes?
