Missing Audio in the end

[tahir]

I have final fanatasy 7 in japanese langauage with higher quality video. And i have the same in english with worse quality. I have replaced audio of many dvd's using these tools.

01. PGC Demux (demux the movie)
02. Muxman (multiplexing with new audio)
03. VobBlanker (replace the movie)

but the problem is that the japanese version is
HH:MM:SS
01:40:54
and the english version is

01:30:27

The english version does not have the end credits.
please help me how can i replace the audio. One idea comes into my mind. and it is to join the end credits audio to the english audio. but i dont know of any tool that can concate ac3 files.

Thank you rolz for pointing me to the right direction. I havent extracted the audio yet. the english ac3 file is 2channel and the Japanese ac3 is 5.1. I will transcode the japanese end audio to 2 channel ac3 and then will join it. I have one more question. When i extract the Japanese end credits will it have delay value. What should i do about he delay value.
