Symantec Management Platform (Notification Server)

I need to know if there is a way to add to these videos that appear on the My Portal Page in the 7.1 Console. We are creating videos for our users on how to perform certain functions in the 7.1 console and I would love to house them in the console instead of a another web site.

You could.  This webpart references WebPartGettingStarted.aspx, which references a .js file and another .aspx (VideoPlayer.aspx).  Once this page is loaded, depending on the context, it will reference a different video.  For example, if you open the Welcome section, it will send the URL src='/Altiris/Console/VideoPlayer.aspx?inputFileName=http://www.solutionsam.com/solutions/public/instructional_videos/welcome.flv"

Now I'm not quite sure how you modify this to be honest with you.  Instead, I would recommend finding a host for your videos, creating a website for them, and creating a custom Web Part that loads that website.  It could be a simple .html page that has several links and descriptions, or it could be a more rich page.  But if you modify the default page, you run the risk of erasing your customizations with upgrades -- not to mention I'm not sure how to add sections here.

There are some general topics about this in the Symantec Management Platform 7.1 SP2 User Guide. You could have a look at the topic Creating and modifying portal pages, and use it as a starting point to see if you find some useful information there.
