I suspect, as with Windows7, a clean install will be the best option. 
Windows7 allowed a clean install, even when you bought an upgrade. (As 
long as you had a previous version). I hope Windows10 has the same 
ability from the downloaded iso.

I suspect you're right about DVDs. Movies have always required separate 
software. I use VLC. Microsoft says that media player will be 
uninstalled because it has issues with Windows10.
