I have a big problem to watch video from a study CD. Recently, I inserted a CD which it starts running in the CD-rom then turn on the menu about this video. When I clicked to play the video, it shows a black content in the small window. Another one which can install the software from the CD but still can not watch the video. There is 2 options to choose and play it ' use Direct X9 video mode' or ' use compatibility video mode' . But both of them don't play the video and pop up ' There was a problem with the DirectX Video Window.' Both CD works on my friends' XP system laptoop but not my Vista.
I have tried to download and install some software , such as DirectX9 but it doesn't help at all . So I don't know if you have any better suggestions please .
