  I looked at some of the USB Port Hub that have 4 ports at popular and was tinking whether to buy as i only have one port left....but i was wondering if the xfer rate will be slowed down?
  
  Lets say one of my pc port have 2MBPS Xfer rate...that means if i attach the 4 port on the hub and then xfer data thro all of the 4 port the speed will be 0.5mbps per port?Is this correct or will it be 2mbps per port?
  
  Another question is that which program can i use to cut away some part of a video i dun wan?

  I doubt it will work like a battery in a parallel circuit.

  If multiple USB devices are sending or receiving data at the same time through USB hub, it'll slow down. If only one device is transferring data at a time through USB hub, it'll be the usual speed as without using a USB hub

  If you asked me about USB, you can throw that 4mbits theory out the window.

  Check that there is space, and your memory card is not locked (the little switch at the side of SD)
