Hello brian beadle! Welcome to the Windows 7 Forums website!

What type of videos, format that is, are you trying to view? What media players are you using?

More information equals, more than likely, a faster answer and/or solution.

Thanks,

As Nibs says, the more info you can give, the more we can help . Any error codes or a description of the problem will help.

If I had to take a wild guess, it would be a lack of codecs - you could give this media player a go as it will play almost anything:
