• Media Player11 will not play video (DVD disc). The sound is fine and a DVD decoder was installed.

  Where to start... After you download the necessary drivers and also I was able to get my sound work. Then, I bought and downloaded the dvd decoder, InterVideo DVD XPack. When I put a DVD in the drive, Media Player appears and I press play and I hear the sound but I do not see any video!

  I tried to download and use other video players, but none have worked so far. Everyone give me reasons why they can not read/play the disc or separate errors. Some have suggested that I change my screen resolution or color quality. I have and nothing makes a difference. Only, I can choose between 800 x 600 or 1024 x 768 (16-bit or 32-bit).

  I suggest you uninstall your sound card in Device Manager (Control Panel - System - Hardware - Device Manager) and restart. The sound card must be reinstalled the next time Windows starts. Who help me?
