I think I might have the answer for you, aok. Here's what you need to do:

1. Play the movie
2. Bring up the menu.
3. From the stream selection, you will have something like this:

Stream 1
Stream 2
-- OGM Streams -- <= Separator, Unselectable
English
Japanese

To get the correct audio, you need to pair up the Stream option with the correct language, so Stream 1 + English for English Audio and Stream 2 + Japanese for Japanese Audio. If you attempt to seek through the movie, you have to flick the OGM Stream to another stream and then back again to get the audio again.

Try this out and see if it works with you, I may just be lucky.
