ME came with PCs that are still good for most on-line content.
So there is no hardware reason why videos won't play: to increase chance that more video sites play?
You can install additional codecs (they help Your player to read and transcript videos - there is more than one way to encode the videos)
e. g. from http://www.filehungry.com/show/codecs
Best chose codec collections and it should state that they are free or freeware.
You download them, remember where they are on Your hard disc drive and then start install by double clicking the installer. Your video player will normally automatically use them.
You can also add other players such as Apple Quicktime, Macromedia Flash... if they are not installed already.
They also read common and fun web content and videos.
p. s. 30 - i got my 1st PC later than You - so there is still hope ;-)
