This is all I can find, might do the trick;
When changing the multiplexer to NTSC or PAL all other settings
are returned to the factory defaults.
The multiplexer can be used with either NTSC or PAL systems.
To set it up for NTSC operation:
1) Turn off the power
2) Press and hold the and {M} buttons.
3) Turn on the power
To set up the multiplexer for PAL operation:
1) Turn off the power
2) Press and hold the and buttons.
3) Turn on the power

You can learn a little about video multiplexers by watching this YouTube video. It's pretty informative:

unplug it for 24 hours and see if it helps

you have to get a demuxer. multiplexing is called muxing, and demuxing will separate the streams

multiplexing is when you interleave audio and video data into one MPEG transport stream

HI Basil, you can get the equipment from PC.
