Video Playlis CSS

Hey guys, this seems so simple but I just cannot seem to figure out how to adjust the width of the left side playlist items in my video playlist. I don’t really need space for the text or titles, but I do need more screen real estate for my video. The playlist also needs to only take up half of the screen. Any ideas? http://www.stageonepromotions.com/cms123/dance-bands/additional-new-dance-band.html

Thanks in advance!
