Remarks
Audio channels are zero-based, so channels 2 through 4 are the three auxiliary karaoke channels. Use bitwise OR operations to set the appropriate bit to send a channel to the left speaker (0), right speaker (1), both speakers, or to no speakers by turning both bits off. These bits are all off by default whenever the DVD Navigator Filter filter enters karaoke mode.
