Before this thread turns into another "My favorite X is Y", everyone please think twice before posting.OP (probably) asked "Which CMS will let me upload and embed videos?", so unless anyone has something to add in that regard, there's no need to state your personal preference.
If, instead, he actually asked "How can I use *just* the video uploading/embedding tools provided by Django CMS?", then his question should be made in their official mailing list, not this one.
My suggestion to OP: please go through the
djangopackages.com list for CMS apps[1]. By that I mean visit their websites and IRC channels, and possibly read through specialized mailing lists. This functionality is probably going to require a great deal of manual configuration as the implementations can vary greatly, so maybe someone out there can show you the way.
Feel free to ask again once you have questions about using Django itself.
Cheers,
