[DMDX] Help Hi,   I'm not sure that the experiment I'm programming is possible with DMDX. I have three large video file that lasting about 12 minutes each.  I need to present these three video files while at the same time present a series of  files.  There will be roughly 2100 wav files played while during the 3 video files are played.  The wav files are only 500 ms long, that is why i need so many.  Is it possible to have these video files played constantly as DMDX plays each audio file as well?  What complicates the situation more is that the video files have sound as well.  Will that be a problem as well?  Thanks a million for anyone who can help me!!!   Scott
