Why on earth would they convert a source like AC3/DTS to FLAC?  I can't see ANY benefit in that.  The loss has already been incurred once they encoded in AC3/DTS to begin with; it's not as if FLAC would recover the lost data...

I don't know about AC3, but if you take DTS and make it FLAC, often you'll save some space without losing any quality.

They don't encode in AC3/DTS, that is usually just the format that is present on the disc, so while the codec is technically a lossy one, it is the original source.

Ah christ.  They were afterthoughts that occurred to me after clicking post.  I suppose I should use the edit button.

As far as what was mentioned about DTS/AC3 being the original source, well, I don't think that that is considered original source, even if that's what's on the disc.  somewhere there is an original, uncompressed/lossless version of the audio for these animes (not released or anything obviously).  They just chose to encode and distribute a version of the movie/episode with AC3/DTS...

EDIT #2 (HAHA!) - In regards to utilizing FLAC on a DTS and saving space, well, that is impressive, and did not know that.  Though, it makes sense, because I feel that DTS is a little bloated to begin with.  To me, AC3 at 640kbps sounds EVERY BIT as good as DTS @ 1.5mbps.  DTS volume levels just seem to be higher is all....  Check out this very interesting study they did regarding audio codecs: http://tech.ebu.ch/docs/tech/tech3324.pdf
