I know this is long but please read through if you have knowledge/opinions about what I'm trying to do....

Would it be possible to pull a 5.1 audio track from a standard dvd of the same movie (assuming theres a 5.1 audio track on it), and remux it with the hi-def video? Has anyone tried this? I wouldn't want to do it with every movie, but some, ie. Behind Enemy Lines (2001), Flyboys (2006), Jumper (2008), just to name a few that I'm sure would sound much better in 5.1
Any ideas on this?

In an effort to match up 5.1 soundtracks to captures that were forced to 2.0 Dolby digital because of a DTS soundtrack that the 1212 cannot detect, I have had some successes and some failures. Out of 20 films, I have gotten approx. 10 to match up using a standard dvd's 5.1 track demuxed then remuxed with a H264 video file with time shifting to match video/audio sync. 3 or 4 just matched up evenly, which was great. 3 or 4 were adjusted through multiple time shifting efforts using tsmuxer over and over until the appropriate voice/video sync was met. 2 were matched after cutting the matched file in half, then adjusting the 1st half to match, then the 2nd half to match, then rejoined with TSCutter......those turned out great, but after alot of tweaking and time, probably an hour each.
For the other 10 that arent being so kind, I could follow the same pattern as the final 2 I spoke of before, but i really do not want to spend 10 hours doing that, so once again, I'm looking out of the box and was hoping possibly the incredible minds that work this forum will be there once again to assist, so here is my scenario......
Have been looking to buy a new dvd drive for a new computer i just put together, but have been contemplating instead buying a BLURAY dvd reader to add to my HTPC and take the dvd writer there now and add it to the new cpu. The new cpu is purely a media server I put together for access throughout my home so it doesn't neccessarily need any great dvd kit.
So here is my question.....Now if I have the BLURAY dvd drive will I be able to pull the DTS track off the original BD the same way I have been from the standard def dvd's? and if so, what software (preferrably free, tsmuxer?) could I use to do this with? Is anyone else currently doing this?
Another option would be a fairly inexpensive(less than $100) editing program that would have the ability to so call "stretch" an ac3 file when it is spot on for the first hour, but 1/4 second off by the end of the movie, which has been a common issue.
I know it may sound like I'm pushing the "perfection" envelope a bit far, but out of about 3 TB of hi def captures, only about 20 movies were ones that I really felt 5.1 would make a difference and in my full theatre, it DEFINATELY does....I have compared the 2.0 original captures to the updated 5.1 files and I can DEFINATELY tell there is a difference.....
Thanks for any input and sorry so long....
