You can go to the link i am providing below and be able to view fx shows online,
Unfortunatly FX network does not make all shows available to watch online, if there is a specific show you are interested in i can check to see if it is available to watch online.
FOX is currently streaming full episodes of some of its programs in select markets. Unfortunately, you can only watch these episodes if you live within that specific broadcast area. Right now those areas include Dallas, Boston, Greensboro, Los Angeles, New York, Birmingham, Tampa Bay, Orlando and Washington, DC. FOX also offers $1.99 downloads on the IGN Direct2Drive site. FOX has deals with several sites to stream its television shows, including the News Corp-owned MySpace, plus Google Video, MSN, and TV Guide.
Yes i am aware of software that allows you to watch certain channels online,
for example http://software.techrepublic.com.com/download.aspx?docid=304760
Unfortunatly as far as i know, and i have been researching this somewhat Fox Network has not affiliated yet with any of these software manucaturers that offer this capability.
