We purchased a 2300 projector for our church.  In order to connect it with the video source we bought a 100 foot S-Video cable.  Unfortunately, the image is very poor quality and seems to have a ghost quality to it.  This only occurs with the long S-Vidoe cable.  Do you have a solution to this problem?  Is there a better alternative to covering the distance between these two items in order to geta high quality image?
