First of all, I would dare say that your plug is the best one around, congrats and my sincere thanks for making it!
If you should have time, It would be worth putting an effort to make it friendlier towards other libraries, I use jQuery on some portions of my site, and this didn't go well with it.
I noticed that the plugin doesn't work in Opera (mac)
In Safari the lightbox effect renders also video transparent, while Firefox renders only the box (white portion) opaque.
Another Idea that might be useful to some (like myself) is to be able to paginate the imported video's.
Hope you find this info useful in case you didn't know this already.
