When installing Divx you can choose what to install. Web Player - Full Player - Codecs Just check the box's you want.
Any player should have the open a url option for streaming. So pick the one you like to use. Or you can simply download the file and open the part file if your player will play part files, or wait till it is finished downloading completely. There are so many way's to do this it shouldn't be a issue.
You will just have to do it manually after Chrome disables that function unless Divx makes a update to fix the issue. All IQS does is basically the same thing.
So pick a player you like/love and watch on
Or switch to FireFox no issues with it.
