Oi!

I got myself a Tevion DVD-3000 (from Aldi/Germany, 80EUR). Nice device, but I got a problem with SVCD playback.
I've got SVCDs with two audio tracks, German/English. With my Toshiba SD-520 I can switch between them by pressing the "ANGLE" button on the remote control.
I haven't had any success with the Tevion DVD-3000. No button does the trick and the AUDIO menu of the player has various options (mono, left, right, stereo) which, alas, have no effect whatsoever...

Any idea?
Thanks
