First you must be a registered A-ha! TV user.

Then...

You can stream any of the following file formats from another server:

    * .flv (the recommended format for video streaming)
    * .swf
    * .mov (second best recommended format for video streaming)
    * .mp4 (supports both video and audio as a format)
    * .wmv (.asf or .asx are not included since they are considered "dead" formats)
    * .avi (utilizing any codec, this includes DivX)
    * .mpg and .mpeg
    * .rm and .ram (Real Media - supports both video and audio as a format)
    * .mp3
    * .wma

Please note that when you want to stream files hosted on other servers, you must use a bot string.

Examples: {wmvremote? }http://www.remoteserver.com/folder/myvideo.wmv{/wmvremote}
or
{mp3remote? }http://www.remoteserver.com/somedirectory/file.mp3{/mp3remote}.

You simply add "remote" after the filetype and use full paths -links- to the files hosted on other servers (including file extensions). Simple, right?

To embed videos into your content use the following strings per video provider:

    * For Google Video use: {google? }video_id{/google}
      For example if the link on your browser displays http://video.google.com/videoplay?docid=-3406925506469882756 then your video_id is -3406925506469882756, that means the characters that come after "docid=". Please note that in some cases there might be a minus sign (-) before the last sequence of digits or not!
  
 * For local Google Video sites (like Google Video France) use: {google.TLD? }video_id{/google} and replace "TLD" with "co.uk", "com.au", "de", "es", "fr", "it", "nl" or "pl", depending on the local Google Video service.
      For example if the link on your browser displays http://video.google.fr/videoplay?docid=-3406925506469882756 then your video_id is -3406925506469882756, that means the characters that come after "docid=". You then write inside the editor: {google.fr? }-3406925506469882756{/google.fr}. Please note that in some cases there might be a minus sign (-) before the last sequence of digits or not!
   
* For Yahoo! Video use: {yahoo? }video_id{/yahoo}
      For example if the link on your browser displays http://video.yahoo.com/video/play?vid=c860df3ccf66c83fb61bb2ffd934330b.1155220&cache=1 then your video_id is 1155220&cache=1, that means, everything that is AFTER the last DOT on the link!
  
 * For YouTube use: {youtube? }video_id{/youtube}
      For example if the link on your browser displays http://www.youtube.com/watch?v=cdXTDovB9K8 then your video_id is cdXTDovB9K8, that means, again just the number at the end of the link!
 
  * For iFilm use: {ifilm? }video_id{/ifilm}
      For example if the link on your browser displays http://www.ifilm.com/ifilmdetail/2732615 then your video_id is 2732615, that means, yes you've guessed too, just the number at the end of the link!

* For Dropshots use: {dropshots? }browser_link{/dropshots}
      For Dropshots we use the whole browser link, for example http://www.dropshots.com/day.php?userid=127444&cdate=20060612&ctime=050513, because this is the easiest way to embed video. You see, Dropshots uses variables inside the link that would otherwise need to be "found" inside the browser link. And our "motto" for the plugin is "no HTML-hassle" at all! So using some extra PHP code, we "clean up" the link and embed the variables correctly in Joomla's content. So all you have to do is just paste the whole link and that's it!
