You will have to split the WMV file up into separate files for each section. You can then create a text file with the extension .wvx that contains the URLs of each separate WMV file. The hyperlink will link to the .wvx file which will load the associated .wmv file into media player. In order to play the whole thing you can create a .wvx file with a list of all the sections in order and MediaPlayer will step through them automatically. There may be a slight delay as it switches to each section. Of course, if you want to have any section play through to the end, then each section's .wvx file should contain not just the URL of it's own .wmv file but also all those that follow it.
