Most video players write directly to the video memory on a computer (hardware acceleration) so that the video can be played at a faster speed, and leave a blank area on the frame buffer. In windows there are two different ways to have a second monitor connected, In order to view the video on both screen you must either tell windows to copy the video memory, as opposed to just sending the frame buffer to both screens. Also, if software rendering, as opposed to hardware rendering were used, the video would be written to the frame buffer, instead of the video memory. I do not know if this can be done in windows media player, but open source ones such as vlc or mplayer can. If the video is written to the frame buffer, instead of the video memory directly, the playback of th video will most likely be slower, or less fps.

I am not on a windows computer right now, but you can tell windows to use the copy mode to display the video in the display properties -> advanced area

If you’re going to do online banking or taxes over the Internet, I was under the impression that it’s all encrypted anyway as long as you’re in a secure session (padlock, https, trusted site, etc.). Even if someone sniffing your wireless transmissions intercepted the encrypted data over the airwaves, they’d have to unencrypt the scrambled data to read and make sense of it. It’s not like it turns into plain text over wireless as opposed to a wired connection. Am I wrong?
