I had made a DVD Video(4.7G) myself.
It consists of 100 video songs. I used TMPGEnc DVD author 1.5.
It is played normally on a DVD player (Chinese made).
But "audio channel change" function(stereo, left mono, right mono, mixed mono) does not responds.

Video type:
MPEG-2 Video(PAL DVD)
Audio type:
MPEG Audio Layer 2 Files
48000 Hz, 16 Bit, Stereo
Bit rate 384 kbps

How to author DVD in detail to resolve it?
