Also, what Scott didn't tell you is that while the technique sounds like you need a MSCSE degree to set it up, fact is the setup with your router is pretty much automatic. Only thing you'll need to do is tell it what common name you want to call your slingbox location pluss select two passwords. The it assigns your slingfinder id which is a hugely long alphanumeric number. The first time setup takes a little longer and after that, installing the players on computers is quick and easy. The main limitation is that since the sling box is controlling your DVR or other video source via an IR blaster attached to the IR input on your video source, it can only be controlled by one location at a time. Once a player logs in, no one else may also watch at an other location.
The cabling is easy as it uses analog video connects and audio. Then you have a dual IR blaster wire with two sensors. Attach one to each of your video sources and then connect your ethernet cable to the router. Now install softwares.
If you buy stock slingbox off the store shelf you will probably need to download the latest version of firmware and player software after configuration with the included software. That doesn't take long either. I was watching my PDA cellphone all afternoon here via my wifi. Worked flawlessly! One other thing, you must have your receiver ise an active analog video connect as the sling box only accepts AV or RF coax on VHF channel. The use of HDTV signals is not used. However, if you have an HDTV receiver and set it to output AV or RF coax,in downres then what you will see on a HDTV channel will be a widescreen slingbox program in the proper AR.
