1) I don't intend to upload videos but rather I want to stream videos from youtube, dailymotion, etc. I am on a share hosting at siteground.com I don't think they meet all the required server requirements but my main concern is for streaming videos only.

2) My main use is for multi-parts movie with multiple episodes. For example, each movie has text links underneath it to click on other episodes which will play in the 'jvideodirect' player.

I hope this would be the last place I stop for streaming videos for multi-parts movie like the one they have at online.film4vn.us/ChitietPhim.aspx?filmId=915

1. If min. requirement is met, video fetching will work.
Just make sure you passed "check up" tool.

2. That cannot be done straight away, you need to add all video and embed them into your article that layout the your image attached
