After you have downloaded and unzipped the files from the web, you may use them directly from your computer:
Upload (some of) the files to your MP-3 player and try if it can
play them. If it does, connect your NBTV televisor monitor to the earphone
output in the same way as to the computer. Do the same experiments as described
Once you know the polarity of the output of your MP-3 player, there is no need any more to store the files of "the other polarity" as well.
In both situations it is very likely that, due to shorter or
longer interruptions of the video signal, you experience loss of synchronisation
of your televisor monitor when it proceeds from one file to a next one. This is
an inhaerent problem of reading file by file.
If you want to play the whole sequence of files without any interruption, you may record a CD Digital Audio disc.
You also may concatenate (glue) the files by using a wave editing program, e.g. Goldwave or Audacity. Then make one file in upright video from the files MUTR00.wav to MUTR20a.wav, and/or one file in inverted video from the files MUTR20a.wav to MUTR40.wav.
