@ Sarah: Glad to hear that it all got solved and working now.

yeah sorry didn't understand what you meant before, and i still don't...
For as silly as the asking may sound, be never ashamed to ask further, when it's to clarify remaining doubts - this is kinda my own "moto".

(And you should see what silly questions I ask sometimes!

But so what!

If it serves to reach further enlightenment...

)
I don't have so much knowledge about the subject myself (waaay far from it, really, closer to none would be more like it!) and wouldn't know to explain in technical details, but, hmm, in a simplish manner, let's say that DivX, while being a
codec for video content, is kind of an "equivalent" to what mp3 is for audio content. Or in some way to what zip is for a file.
It's a compressor/decompressor or coder/decoder (hence
codec), meaning that, just as you need to have installed the required mp3 codec both for being able to create .mp3 files and/or to play them or play for instance any video file which has audio encoded as mp3 (as for example those .avi videos of "Boston Tea Party" which I made), or even as you need a zip program such as Winzip or Winrar for being able to both zip and as well unzip a file (otherwise you won't have access to the file inside and won't have the possibility to extract it); the same way you need to have installed the required specific video codec for being able to watch the video content of a video which has been encoded with that certain specific codec (namely in this case, the DivX codec), otherwise (just like in the zip analogy) you won't "have access" to the video content (precisely, since you lack the codec for decoding the video content) and so won't be able to watch it.
Overall, I did choose to encode those .avi videos with DivX for the much DivX is popular and commonly used/widely spread... (Thought, nowadays, virtually everyone would have it...

) Anyways, good that you got the "no video" issue sorted now...

As for what's necessary and what's not:
now i'm just wondering what part of that divx i can delete again, have a divx converter, a divx player and divx movies on my comp but don't think i need that all do i?
That "DivX Converter", "DivX Player" and "DivX Movies" you say to "have in your comp"; I assume you're meaning those 3 new shortcuts that got in your desktop?
Well, the "DivX Movies" at once, it's really only a shortcut to the Movies sub-folder within the DivX folder in C:\Programs (I suppose where any videos downloaded from within the DivX Webplayer are to be stored), it ain't even a shortcut to any program, so you can simply delete that from your desktop of course.
As for the other two, the shortcuts to "DivX Converter" and "DivX Player" in the desktop, well, it's also really only shortcuts, so can be deleted as well, if wished. (Removing the shortcuts from the desktop doesn't however remove the respective DivX bundle components, i.e. the DivX Converter and the DivX Player programs themselves, as obvious.

)
You can, though, individually remove any of the DivX bundle components, if you wish. (Go to Start > Programs > DivX, and besides a full uninstaller for the whole bundle, you'll find in there an individual uninstaller for each of the components: the Codec, the Player, the Webplayer and the Converter.

) I suppose the one only really essential component to keep is, obviously, the codec (that's what you do need for being able to watch any video encoded with DivX). All the other components, and whether to keep them or not, I guess it's really just a matter of personal choice/preference.
DivX Player - Up to you. Plays various video file types including .divx files and .avi files encoded with DivX. But should you not want to keep this additional media player, so long that you have the DivX codec installed, you can of course play .avi's encoded with DivX in default Windows Media Player, as you can perfectly also play there any videos with the .divx extension, (at this point at least) it's not mandatory that you have the DivX Player for playing these.
DivX Webplayer - Up to you. Sort of a plugin for playing .divx videos in the browser. Let's say it's an equivalent to the Flash Player for viewing flash videos on websites. Respectively, for viewing .divx videos on websites so you'll need the corresponding DivX Webplayer. (Don't know how much common it is to come across such videos in websites, at this point, though? Either way, in the event that you miss the DivX Webplayer plugin, your browser should notify you when you try to view such a video online, and prompt you for install, I suppose...)
DivX Converter - Up to you. As roxflower was saying, this is supposedly for converting videos to the .divx format. Then again, it's also only a 15 day free trial, so...

On the other hand, it is also possible to choose which components of the DivX bundle to install during the own installation process. (Should you ever wish to uninstall the whole bundle and later wish to install only certain components instead of it all again.) Then, just untick the corresponding box for any component you don't want to install and leave the checkmark only on that/those you do actually wish to install, and off you go.

(I myself, for example, usually install only the Codec and the Player and the Webplayer, yet not the Converter neither the Content Uploader. If I'm not supposed to use those, why would I anyway?

It's up to each user's choice and use, really.

)
Anyway. Hope some of this may have helped to "clear (some)things up"...

Do enjoy the videos after all.
