Rick, I have used JWPlayer extensively together with many others (RadiantMedia player, FlowPlayer, THEOPlayer), JWPlayer had been very good but their charges kept on increasing while removing features, until I found EVP (Easy Video Player), written by someone from Romania and the guy is very supportive in terms of player setting up,  a little code change let me import player code and the only code I have to insert is for video source and video poster.

EVP is so feature filled I haven't seen ANY (Remember I have done extensive research on players) , where all others players charges extra for things like Ad Support, HLS Streaming, Subtitle Support, EVP has it all in one player, and best of all its ONE time payment only for life time updates, unlike many others charging extra for features and on monthly basis. 

You can check EVP HERE. 

You may can wait a little as sometimes he brings down prices to as low as $25, but for a better deal (his all players, scripts, codes included) you can buy all his stuff for $99 HERE.

EVP will not provide you with hosting, but you can always use YouTube as streaming platform, keep video unlisted there and play within your EVP Player on your site. 

Craig,

Absolutely right in terms of shared configuration. 

regarding DB, you can use any prefix, but be assured it remains same when merging tables, as on local installation moodle points to table name, and in case of difference once merged, it will create issue. 

moodledata is configured in config.php file, if some portion of the content are called in from central repository then it's ok, moodledata's local folder will serve images, parts of selected theme, user cache and anything uploaded on that instance (which will later be replicated on to other moodle sites's moodledata folder anyway). you can setup moodledata to be used from parent (central repository) but it will impact the speed of moodle. 

If you have softaculous, means you're on a managed server (either shared, VPS or Dedicated), delete everything (moodle, moodledata folders and database) 

download from moodle.org and manually install moodle creating DB first. 

which hosting provider are you with? as resource limits sometimes effect rendering of the pages, your hosting may be hitting I/O limits, whilst your friend's doesnt. 

Chris, WPI is as same as script installers with hosting providers, and they are strictly prohibited to use. 

I had created a tutorial a while back on Server 2012 R2. Server 2016 and 2019 has exactly same procedure, you can follow tutorial HERE.
