How to remove a Bookmark?

Although my Apple remote only scrolls web pages up and down, I am able to use a Mac mouse to navigate the cursor and click on links when surfing.

However, I have bookmarked a page that now crashes ATV flash when selected and would like to remove this bookmark from my bookmark list. Does anyone know how to do this? Also, is there a way to organize bookmarks in couchsurfer?

Finally, when I click a “play video” link (e.g., on the Apple web site), the Quicktime file does not play despite having installed the Quicktime plug-n using the choice available in the atvflash’s menus. Is there a fix for this; for example, is there a way to install the plug-in directly?

Thanks, Phillip
