Ok, thanks to feinicks I was able to locate a remastered Outlaw Star, have to wait until I get to work to dl it, but half of it is single audio Japanese.  I did some research, found a program called MKVMerge and MKVExtract.  I have the old version of the series in ogg format, dual audio.  If I rip the English audio from the ogg file and remux the mkv, will that affect the video quality at all?  I'm guessing no, just want to be sure.

K, I called a friend of mine, he's downloading a couple of the single audio eps, gonna play around with it tomorrow.

And thanks fer the pm.

No it wouldn't. As for why, read below.

You are correct in that it woudn't effect the quality. But re-muxing doesn't take a lot of work.

Muxing (multiplexing) is simply the process of taking all the separate streams (audio, vidoe, subs) and putting it into a single container. It does not change the actual streams, thus will net effect the quality at all. Direct stream copy, so you don't need to re-time or anything like that. Doesn't take much work at all, should take like at most a few minutes to do. (As opposed to encoding, which can take up to a ridiculous amount of time. Use enough plugins, and high enough settings, and it can take you 6+ hours for a single pass 25min episode. People often do 2-3 passes.... muxing is nothing.)

And regarding the increase and decrease of file size, it depends on what extra stuff you add in, or take out. A re-mux with exactly the same stuff shouldn't increase in size much. Also depends on the container. Some containers have more overhead than others, but that difference is likely to be very small.

EDIT: If your muxing stuff from different sources, then there may be a sound mismatch.

i would try a  "Direct stream copy" and remux, if the sound is out of sync i won't try a next episode,. because if i am correct then you have to encode again,. so if you lucky the audio file matches the video and you can make your own mkv files with your own audio files in it.

Generally taking streams from one source and combining it with another will cause desynch (it's typically by a constant factor).
If I recall correctly MKV can offset streams with delays though, so it may take a few tries to get the synch right.

Oh, since your audio and video come from different sources, there may be an audio mismatch.

If there is, shift it forwards or backwards a bit in MKVmerge. Don't actually need to re-encode.

EDIT: Pretty much the same as the above post? Yeah, you got in slightly before I did, while I was typing.

Moving truck coming through!

Called a friend of mine at 2am to get him to get the remastered episodes (he was grumpy fer some reason), been playing around with mkvmerge.  I used ogmdemuxer to extract the english audio and have been playing around with the timing.  Its surprisingly easy to do, the process, that is, but getting the timing down can be a bitch.

Doesn't MKVmerge accept OGM files directly? (I'm pretty sure it does)

So you don't actually need to demux the OGM. Just directly load the OGM into MKVmerge.

Yep, muxing is easy. (Unless you want to mux into some weird format which doesn't have a convenient tool to do it with).

As for timing, lucky your 2 videos go at the same speed. Otherwise you may end up with an increasing desynchronization, and that's much more of a bitch to deal with. (Like if one video is NTSC, and the other is PAL sped up by 4%).
