I have downloaded & installed Java but the videos still won't run?

Answer 1

If you can't see them, download them.
For any kind of Videos there's YouTube: http://www.youtube.com/
To download videos from YouTube and any other site :
Get Firefox from http://www.mozilla.com/en-US/firefox/
And then install the Download Helper extension from https://addons.mozilla.org/firefox/3006/
It works great for me.

Since the videos are in the .flv format you need to get a flv player. You can get a very good one (and completely free ) here http://www.download.com/FLV-Player/3000-2139_4-10505954.html?tag=tab_pub

Also you can use this site http://javimoya.com/blog/youtube_en.php and copy/paste the url's from the page with the video there but personally I'd recommend using Firefox

Firefox is the best !!!

And for movies and anything else use http://www.torrentportal.com/ and http://www.bittorrent.com/ and http://www.torrentspy.com/
To download from this site you need a torrent program like these :
BitComet http://www.bitcomet.com/ or
Azureus http://azureus.sourceforge.net/

Answer 2

It would help if you gave a link tot he videos or told us what type of video it is, you may need Real One Player, or quick time player..Windows Media Player is usually used.. You can get the latest of each of these from www.download.com or their manufacturer's websites. If you are using Firefox then you can go to the java site and get a small plug in for it... Java may only be installed to Internet Explorer.
