What happens when you try to watch these videos online? What error messages do you get?
Also, which browser are you using? EG, Internet Explorer 6 or 7 usually has video player plugins already installed, or the plugins can be downloaded, but a browser like Firefox may need a special plugin to play some videos inside the web page.
I enjoy viewing various news, humor, etc. videos online but DO NOT want to download them just to view them. In the past I never had much of a problem but it seems now at least half don't play. I understand there are more formats which may be the problem but is there anything I can do so I can go back to clicking on a video and watching it........that simple?
I have an HP laptop running XP with SP2. I tried and download and or update Quicktime, Flash, MediaPlayer, etc. to see if that would help but to no avail really.
