Question About DVDx



I have software called Number 1 DVD Ripper that is supposed to reduce video file size by converting the video to DVDx format.

Can someone please tell me if the average home DVD player for a Television set can play DVD discs in the DVDx format?

About how many hours of video should I be able to I get on a single layer DVD disc using the DVDx format? I am willing to sacrafice picture quality to get more hours of video on each DVD.
