The fixes may not be necessary, depending on what changes you have made.
They should only affect internet explorer - if you load up your site in IE and click on a video link / login link that is connected to thickbox, what you have to look at is does the overlay (the darkened area) cover the whole of the width of your page or not?
If it doesn't, this means that the body tag width is not being set as 100% by the css. In the yget template for example, it seems that the body width is set to only 90%, meaning that the overlay will only cover 90% of the screen also. Really, it should be the containing div (#wrap) that is set to 90%, and the body width should be left at 100%.
Btw, if this proves to be bug free, we should think about converting the mods that use lightbox (there are a couple I think) to use thickbox. I think they will be interchangable.
