ok, i've read the thread a bunch of times and i have a couple questions still. i believe this thread is for posting questions, so here goes.

1. when u demux the desired streams, are u supposed to end up with 2 seperate files? one video, one audio? or are u supposed to just be taking out the other audio streams and keep it as one .m2ts file with the video and audio that u want?

2. step 3 in ryu77's post says remux the video only for compatibility. is this step supposed to take really long? like 25-30 hours in total? (i know it depends on ur computer specs and i g-uess the remuxing profile you have selected) i feel like i could be confused, but it seems like my computer takes about 8 hours to do job 1 in megui which is creating a .avs file.... i dont even know if thats right... and then in takes about 20 hrs to change my demuxed video file into mkv format. the resulting mkv files is about the same size and the demuxed video stream from the original blu ray disk b/c then i have to furthermore re encode the video with audio at a lower bitrate to make the file smaller.

i dont know if i'm making sense. please ask me to clarify if i'm not. in brief summary, i am just looking for a .mkv video file (with video and audio obviously, encoded with .h264 codec) that is much smaller, around 4-8 gigs. and the steps as i understand them are 1. rip video 2. demux selected stream of video and one desired audio 3. create .avs file and then change video to .mkv file 4. re encode new .mkv video file and audio into smaller .mkv file?

to shrink use TsRemux to shrink your blu ray backups to a smaller size:)

to watch with AC3 track with the m2ts, this ...this is golden!
use mediacoder
http://mediacoder.sourceforge.net/
you can use that to bring it to a MP3/AVI file for you to view!

to watch with a DTS track with the m2ts, i suggest loading the m2ts files into VirtualDubMod (note: set to Xvid-24bit-5Mb/s compression) which will convert them to AVI , this will leave you with about 6gbs of files (including DTS audio, so you'll have a combo of the DTS files and your newly encoded AVI files), you then watch them with just about any media player.... i hate to break it to you at the moment this is the only working method i have found for DTS audio, it leaves you with about 3 gigs of video and 2-3 gigs of audio....

For example let's say you have a movie that has a run time of 2:10:14. That would be 7814 seconds. Now you have to determine the output size: a DVD+R (Dual Layer) holds 8,547,991,552 bytes or 68,383,932,416 bits. Divide that by the number of seconds and it means that, without any other considerations, you have a total of 8,751,463 bits per second (about 8751Kbs). If you assume a 6% overhead you will come to about 8400Kbs. Being the careful type I usually even take a little more off (because it takes lots of hours to encode, I don't want to oversize and have to do it twice). So let's round it down to 8200Kbs.

Now subtract the audio track. Let's say you are keeping one of the 640Kbs AC3 tracks... 8200 - 640 = 7560.

So you'd replace the 5240 with 7560 for that movie.

Here are your best steps to recompress a Blu-ray disc to fit onto a DVD-9 (BD-9) or DVD-5 (BD-5)...

1) Load your main movie file into tsMuxeR. It will usually be the biggest file in this directory: BDMV\STREAM\00000.m2ts.

2) Demux the desired streams (advisable to select regular Dolby Digital (AC3) or DTS. Dolby TrueHD, DTS HD Master Audio/High Resolution Audio or PCM 5.1 (uncompressed audio) are going to inflate final file size too much.

3) Remux video only (no audio) into MKV or MP4 container (MeGUI, YAMB or MKVtoolnix are recommended). This step is not 100% necessary but I use it to increase compatibility with different encoding applications (or AVIsynth).
