I often watch video off the Internet from the webpage itself – e.g. Hulu and YouTube. Sometimes while watching it I got distracted off the wording and advertisement. I know its not a bigger deal but sometimes I just want to watch that small box of video, nothing else.
Thats to Zorro this is possible. Just run Zorro, resize its window according to the video you want to watch, press ESC. Everything on the screen will become black except that define region. Zorro (http://www.gabrieleponti.com/software/index.html#zorro)
