I have the Slingbox PRO Its good if you want to use multiple sources for the video (DVR, Cable, Computer, DVD Player)

Slingbox SOLO ( Has allows you to connect to (1) video source that has component or RCA)
Slingbox TUNER ( Has only the tuner so you can plug in to just your standard cable)
Slingbox AV ( Has only (1) RCA In)
Slingbox PRO ( The mother of all Slingbox's it has the tunner, and you can plug in 3 other devices via the HDMI port the RCA and the S-video)
