Do not connect the Roku 'thru' a DVD player (or any other accessory). If you don't have another A/V port on your TV get an AV switch. If you're using RCA composite cables (RWY), then you could use something like this:http://www.amazon.com/Sima-SVS-14-Input ... 347&sr=1-4
You can use something like that for component too (not the model shown, but another one ( http://www.buy.com/prod/atlona-at-cv41r ... 09470.html
However I disagree (respectably of course).
Those cheap switches (like the one you linked too) look like junk and introduce noise and such (since they use cheap parts to keep the price down).
If the DVD player has a true "pass-thru" then it should work perfect.
I use my N1000 (what people call their "Roku") to my other Roku branded video piece which is the HD1000 (their DVP from 2003) and the HD1000 has a pass-thru and that looks stellar for both the HD1000's picture and the N1000's picture in pass-thru.
I bought one or those switch boxes a while ago for a project and one one I got was not $16 but $39 and it was nasty, so much so that it's not being used and I think I thru it in the trash last week (what are the odds, I have had it for over a year). If I still have it, I'll post back here and if someone pays shipping, they can have it.
Just my 2-cents, Matt
