The big hump in the SD DVD early days was the Mpeg2 video encoder/re-encoder. Although there were a couple PD types, commercial encoders (like CCE/Cinema Craft Encoder) was, and is still, the best. But at several hundred dollars, 'cracked' versions flooded both usenet and the torrents. Audio, whether Dolby or DTS, was playable (and decoded) by most players, and processed by most audio/receiver setups, so although the DTS was considered by some to be bit-excessive, the quality greatly
exceeded Dolby.
Today, the situation with BR is precisely reversed. x264 is a PD encoder, used by virtually all the recode mechanisms out there, including BR-Rebuilder and others. But the audio landscape, with Dolby TrueHD and DTS-HD Master (both 7.1 streams), is where the problem is.
DTS did DTS-HD Master right, in that any 'standard' DTS decoder can decode the 'core' DTS within the HD-Master stream. Dolby, however, didn't do the same with TrueHD. You'll find, on usenet, that many soundtracks of both types (and the occasional uncompressed PCM 5.1), are processed via a program called 'Eac3to' to either 'standard' DTS 5.1 (full rate 1.5mb/s or half-rate 768kb/s) or Dolby 5.1 (generally
640kbps). Both need, however, commercial encoders to do the processing, but again, 'cracked' versions are available throughout the internet.
Since the audio is constant, and not variable compressed like the video, the bit-space it uses up (particularly the HD audio types, at ~3.5Mb/s rate), are ripe for processing (especially as only those with the newest receiver/decoders have the capability for the HD audio streams). Also, additional audio such as commentaries can be further squeezed by using highly compressed formats, such as OGG, IF the player supports it (like some networked media players, aka Popcorn Hour et. al.).
I've been d/l'ing a lot of 'full' BR rips, and lots of posting folks seem to think (just like with SD DVD's), that stripping out different audio streams (foreign languages to commentaries, and captions) to save 3GB out of a 50GB posting makes sense. Makes zero sense to me. One spends x hours to upload, and quibles about the extra few minutes it would take to include things that lots of folks would like to have.
Anyway, there's many 'guides' out there (Videohelp.com is a great resource), to put together a list of programs and techniques to achieve what you are trying to do.
