question about audio stream on vcd

[mrvideoconfused]

I have a VCD that has two langauges, english and Japanese. I use ISObuster to rip the vcd file format into mpeg1 format onto my computer. I can play the resulting mpeg1 file on my computer fine. Both Japanese and english are present in the mpeg1 file. If I move my wave slider (in volume control) to the left i I get all english and to the right I get all chinese.

The problem is this, I have tried reencoding the mpeg1 file into a smaller file so i can play it off my pda. For some reason tmpgenc will not detect/encode both audio streams it only encodes the Japanese stream. I did a mutiple 1 minute encode tests and each resulting mpeg file only has one audio stream. All in Japanese

Next I used audio/normalizing feature in tmpgenc to see if both audio streams were detected and I found that tmpgenc only detected the japanse stream and not the english one.

I tried simple demutiplex, de-mutiplex and the audio file from the video file and I got was japanese, the english audio stream was gone.

THe strange thing is that if I didn't re-encode, but just did an edit of the credits or a section of the movie the audio streams would remain in tact.

Another strange thing was that this only affects this VCD/mpeg1 file. I have other VCDs/mpeg1 that were re-encoded with no problems using the same settings. Those files have both audio streams still in tact. Actually when this VCD/mpeg1 file didn't work I tried another one and going through the same steps i had a smaller mpeg1 with both audio streams present.

So how do I get both audio streams or at least get the stream that I want? Both audio streams are present on the mpeg1 file when I play it without editing.

Not sure if this will work but might be worth a try. Use Tmpgenc mpeg-tools to de-multiplex the VCD to seperate video (.m1v) and audio (.mp2) files. Now re-encode just the video section how you want it, then re-multiplex the newly encoded video stream with the audio saved out earlier.

Hope this helps.

The minute I de-multiplex the mpeg1 file I lose the english audio stream.

It's very weird. Yet it lets me edit fine in tmpgenc.
