The titles of the Posts already brought up do not seem to address my problem, so I will post it here. I have Windows 7, and the latest version of Windows Media Player. For some reason, I cannot navigate forward or back in the video. For example, I got to the section 3 Word Study portion and was around the 2 hour mark when I stopped. Now when I go back to that section (word study), I cannot get to the 2 hour mark...it only starts at the beginning. Is it the DVD or something else? I noticed the DVD doesnt have "tracks" to easily navigate around with like a CD would or even a regular movie on DVD. Can anyone help?
