If you want YTCenter loop, aspect, etc to work, set NoChngPlr to true. If you want YTCenter to be able to re-size player, set YTStage to false. If the styling isn't there, re-load the page again, as it was downloading the css. Use if you don't want a white comment background. The HTML5 player style changer is completely made by me, though. That player changer was originally made by Takato, and is under the license for right side description (AKA Better Watch Page) Though that player changer is practically useless now because they removed Player 3. This script includes a flash player changer, which defaults to Player 3 V8. (I store most of my CSS in it to make life easier) Settings are inside the script and have descriptions of what they do next to them in comments. Restores the TestTube Cosmic Panda experiment from 2011, along with the video size changers, and the overall style (mostly).
