It's possible to watch your own videos on the Sim-TV. You must put the video you want 
into My DocumentsEA GamesThe Sims 2MoviesBroadcast (the TV sender you want). If you 
then turn on the TV in the game you can watch it! The video must be .avi-clips and the 
clips shouldn't be larger then 128x128 pixel also it shouldn't have more then 15 frames
per second.
