I either get a black screen or what looks like a TV test pattern or similar (vertical or horizontal colored lines) when I try to either play a video or use Skype to make a Skype call. I can use ANY third party video player (including Windows Media Player, VLC, mplayer, etc.) and ANY video and/or video format (.mpg, .mp4, .xvid, .avi, .mkv, etc.) and I get somewhat similar results.
What do all of these applications have in common? What could be misconfigured on my computer? How can I fix it?
The screen doesn’t go entirely wonky, just the play area. I can view YouTube videos and Hulu.com just fine, it’s just the third party videos and Skype calls.
Thank you in advance for any help.
