I never tried the N1000 Component and wonder if anyone here that has the old Roku has tried it from the component output.
I have an old Roku (purchased in May 2008 when it was called "Netflix Player") and when I first hooked it up to my old TV I tried component. The bootup screen was clearly visible, but once it finished booting the TV would display colored squiggly lines centered and running roughly halfway across the screen and about half an inch up and down from the center of the screen.
It was at that time that did some digging in this forum and saw that the component output is interlaced during bootup and switches to progressive once fully booted. I dug out the TV manual and saw that the TV handles only interlaced, no matter what inputs one was using.
When I replaced that TV with a HDTV, I never retried the component with the HDTV; that night I used composite video and the next day I purchased a HDMI cable, changed the "Display" setting on the Roku to HDTV, and the day after was when Netflix had its promotion of streaming "The Wizard of Oz" for free (i.e., free even to non-members).
If you really are interested, I could try the component cables from the Roku Netflix Player to my HDTV. However, when I hit Info on the HDTV remote, the TV doesn't tell me that the signal is progressive vs. interlaced, just that it's 480. (My old DVD player has a button to switch its component output from 480i to 480p, and it is feeding the TV through the component cables, so I know the on-screen Info doesn't show i vs. p.)
