I finally gave in and picked up a Slingbox last night and it's working fine.

My non-Slingbox AV set up runs through an AV receiver (which handles most of the switching and then feeds the tv).

I currently have the Slingbox connected to the extra RCA composite output on my Directv/Tivo box.  The AV receiver is fed via the (only) S-Video output and a digital audio connection.

My question is whether I should hook up the S-Video output to the Slingbox and then use the pass through to feed the AV receiver to the TV?  I have two concerns:

(1) Whether the video quality on the passthrough will be ok?

 and

(2) Whether I will notice any audio/video synch problems with the S-Video signal being delayed through the Slingbox, but the audio going direct to the AV receiver via the digital audio connection.

Thoughts? 

Thanks.
