Problem with retail DVD and audio track(s)

[TheCoza]

Not sure if I'm even putting this in the right place, but I have a retail copy of Dragon Ball Z Season 1 Remastered.
However, I've had it for a few years now, and when playing one of the episodes, the American audio plays the Japanese one simultaneously.
I don't believe it was like this when I first got it, and as stated, it's too old to be taken back now. It's only one episode, and clears up on the next one.

Cheers for any help.

Edit: I should clarify that it's not just a set playback program which causes this issue. It can be a DVD player, WMP, or even a Xbox 360. They all seem to retain it.

Try play it with VLC Media player, open the dvd or dvd folder, play the episode, try and see if you can change track under Audio->Track in VLC. If not it's probably just one audio track.

And listen if it's american audio in the left speaker and japanase in the right speaker.

Yes it was.

Yes it was.

Nope, the retail dvd just magically remastered the audio tracks all by itself while sitting on a shelf!!

To clarify: it is not possible under either the CD spec, the DVD-Video spec, the DVD-Audio spec, the SACD spec or the BDMV/BJ-J spec for a software or device to simultaneously play 2 tracks (not counting out-of-mux popup sounds in BD here, just the main streams). So if you are hearing 2 languages, it's because they're on the same track.

Hopefully, like Baldrick says, they're on different speaker channels. If so, you can rip + demux + process the audio + remux + reauthor to get where you want (though there will be some very minor loss in the processing/re-encoding).
If they're on the same channel, you're out-of-luck.

Are you SURE these are legit retail discs? It doesn't sound like it.
