Embed video customization in Wordpress

I need a solution to: 1. get videos to stop playing when switching between video mirrors.. 2. get videos to auto size between small player and large player with w=100% h=100% -- set the player size.. heres the page: [login to view URL] #1 - you can see that if you play the video on this page and then select a different video mirror above the video, that the video continues to play in the background. I need a solution to this problem. the video needs to stop playing when they click on a different video mirror.. #2 - so the problem im facing is that all the video mirrors have set size parameters: the problem is im doing 2 different size templates for the watch page a large and a small.. the small player is 480x400 where the large page is 660x400 .. is there a way to set the template up with a div box or whatever for each view.. and then i can just input the embed code as h=100% w=100%.. and have it size itself to the correct size? small view: [login to view URL] large view: [login to view URL] so no matter which view they were on.. the video would size itself to the according width and height? let me know if you have any questions. - Aaron
