When you load a video, the slider shows the entire video has been buffered, when only a small portion of it has been buffered.

Victoria is working with me on HTML5 video in Chromium. This change looks good to me.

Thanks Alpha for looking it over.

Just a few minor nits to address.

ChangeLog entries tend to wrap text somewhere around 80 columns.

Two spaces before =

Please add a period to the end of the comment.

I'm not sure why you initialized "double bufferedWidth" with 0.0 above but are using 0 here. (It doesn't matter but inconsistency raises flags for me.)
