What is the best way to hook a roku box up to my system? All audio runs through my sony receiver to the speakers (I don't use tv's sound)

current components:

sony str-de998 (tuner)
sony dvp-cs985v (cd/dvd player)
go.video dvr 4100 (dvd and vhs player)
direct tv's H-22-100 (dvr)
panasonic th-50pz2700u (television)
would like to add roku's 2100X


not even sure if adding a roku box is even possible?

Hoping FadedMaster reads this.

Is the Sony an AV receiverP
Do you have extra inputs? and what type?
What type output on th Roku?

The Roku I have merely has two output cables for sound and one for audio, ( the normal three wire with plugs)

You can use an individual wire to runs to the sound input

The best way of course for me, is to set it down and look at where the cables best fit into your components

This link will show the back of the Sony receiver... yes, its AV capable and being used as such.

As its setup currently, I use TV/SAT/ DVD, VIDEO 2, VIDEO 1 and the assignable component video TV/SAT in; think I'v used up all the available inputs!

The only one I see not being used on the sony receiver is the assignable component DVD in.

That's why I thought I may have to use the DVR's (direct TV H22-100) input for the Roku Box.

Thoughts?

p.s. back of the Roku Box can be seen in this link which shows the outputs available.

How about Component cable out to Component in on receiver?
