Code for Embedding Quicktime Movies in Web Pages-Question

Question

I have been embedding QT movies in web pages for years. I used to use the embed and object tags, but due to the problems with the default settings of IE7, in regards to ActiveX, I recently changed to the javascript method.
I will paste sample code below, of how I use it, with the movie title change to sample: (of course I change the dimensions, depending on the movie size.)
<script language="JavaScript" type="text/javascript"><!--
QT_WriteOBJECT('sample.mov', '644', '76','','controller','true','autoplay','true','showlogo','true','cache','false' ,'enablejavascript','true');
// --></script>
and I put at the top of the page, right before </head>
<script src="AC_QuickTime.js" language="JavaScript" type="text/javascript"></script>
I forgot where I got this code. Perhaps from someone on this forum, or elsewhere. It seems to work with the default settings on most browsers.
I have a couple questions, however, regarding fine-tuning it a little more.
1) If it takes a while for the movie to load, users who open my pages see a static Q QT icon. How would one make the icon flash, with flashing text that says "Loading", so that the user knows that the video is loading? (I have seen that on other sites, and don't know how to do that.)
2)As said the javascript works with most browser default settings, as most have javascript enabled by default. But what if a user does not have javascript enabled? Could the code sense that, and if non-existent, tell the user to enable javascript? Or, if javascript is disabled, could the embed and/or object tags be activated?
3) The code above, that I got from someone, says "cache=false". That means that each time someone sees the movie, it has to be reloaded from the net, and not from the browser cache, correct? If so, why would one want it to be set that way? If it's a large movie, a user with a slower computer and/or internet connection would certainly prefer if it could play from the cache the next time, loading much faster. Is there any reason to prefer "cache=false"?
4)Is there any code that could be put in, to allow the user, if they prefer, to download the file,(perhaps with a right-click or CTRL-Click), instead of playing it in the browser?
Thank you very much in advance, to whomever can help with these code questions.

Answer 1

Thank you for your reply, Kirk,
1)Yes, I do have "fast start" enabled in my files, and they were made with QT Pro, newest version. So no, there is no "trouble with my files".
However, I would still like to have that flashing "Loading" icon when the file is loading, as I see on other sites. (And yes, even with "Fast Start" enabled, depending on the size of the file, the speed of the computer and internet connection, it can take a little time beforeit starts.) Anyone know how to create that flashing "Loading" icon, rather than just the static Q?
2)I just wondered if there was a way for the javascript to recognize if the user does not have javascript, and bring up a message if that is the case, telling the user they need to enable it to see the content. (As would happen if the user does not have the QT plugin installed.) Yes, I realize it would not work to include in the normal way the embed and object tags as well, I wondered if there was a way to invoke them only if the user doesn't have javascript. Perhaps impossible, but I thought I'd ask, in case someone knows of a way to do that.
4)Yes, I guess I could just put a separate direct text link to the movie file for downloading. I just wondered if there was a way to put that in the javascript, so that if someone right-clicks on the QT icon, they can download rather than view it, rather than use a separate link. That may also be impossible, but I thought I'd ask, and see if there is a way to do that.
Your question to me regarding dimensions--I forget which was the QT movie, that I took that sample from. Yes, I have some in unusual sizes. They are not normal movies. I don't have time to explain more now though, and that has no bearing on the questions I asked.
Once again, thanks for replying, and if you or someone else could help further with my questions, I would appreciate it very much.
Have a nice day!
