Hello again Deb. It's better to post just one question per thread as that makes it easier for people to reply to you. (Here's the forums help page) So I changed your title to reflect the second question, as I think you already asked about posting handouts in another forum thread but here is the documentation again just in case: File resource settings
If by live video streaming you actually mean people having a video conference via Moodle then there is something called Big Blue Button which can be added to your Moodle to do this - Moodle as standard doesn't have the feature. If you mean videos playing live, well, Moodle won't set that up for you but you can certainly link to a site where live streaming is taking place.
