Removing audio and adding it to new video...help

[dandad1]

Hey guys, new here and I have a 2 part question would greatly appreciate any help I can get.

First I need to remove the english audio from an ogm file and then add it to mkv but I want to do this without loosing any video quality or having to mess with the video at all. If possible I might need a program that lets me align the audio if it doesn't line up perfectly as well.

Why if you care to read:
I got a full show with great video quality but only 12 out of the 24 episodes have english audio, So I downloaded the lower quality episodes with english audio and I want to transfer the english from the low quality video to the high.

Never mind guys I figured it out,

First you unmux the audio track using VirtualDubMod and that gives you an ogg audio file, you then open mkvmerge add the video you want to put the new audio on, then you add the new ogg audio file and then you remux it, it takes about 20 to 25 sec.

The only problem is the audio is off so before you remux you need to select the audio file you just added click on format specific options and then add your delay, I had to figure it out thought trial and error it took about 5 try's but I got it, one way to help is to watch the video and count the seconds between when someone talks up to when you see there mouth move and then to convert those seconds into milliseconds (1 sec = 1000 milliseconds) and that's it, very easy.
