Q: How do I watch videos on my ipod with my xbox 360?

I plug in the ipod into the usb port. I can listen to music, but when I go to select the ipod as my video source it isn't highlighted and wont let me select it. I don't have this problem with music, but I do with videos.

I want to watch videos using my ipod as usb hard drive source, not converted ones for that I use the special cables for ipod to plug them into the tv.

I now want to use my ipod as a hard disc drive (big usb) because of it´s capacity but won't recognize it as a usb source, when I plug any other usb I can play them perfectly.

Why I want to do this?:

Well I download my favorite tv series episodes as divx, and I do not like to wait until they convert and sync them into the ipod, this takes me around 20 min per episode. Other way I found is to copy them as soon as I download them to a usb and plug them into the xbox 360 and watch them, the problem is that my usb is 2 GB and if I want to watch more than 4 episodes I have to go back to my pc after I watched some of them, erease them and copy the other ones, so I tried using my ipod (60 GB) well around 10 GB left for coping more than 10 episodes at the time and that way I do not have to go back to my pc in all afternoon just keep on playing the next episodes. Also want to watch full music concerts when partying

So really need a way for my xbox 360 to recongize my ipod as USB so I can play them all day long

PLEASE HELP
