Moving this to Home Entertainment, since it's really not a capturing topic...
You do know that these degrade video quality, right? The more cables/components you add to a signal chain, the more likely degradation will occur. This makes power line filtering (via a
good UPS) and quality cables even more important.
I've never seen one that has 6 inputs -- only 4 inputs.
There is this one:
Cables To Go 40697 6x2 Component Video, Stereo Audio and TOSLINK Digital Audio Matrix Selector Switch (Black)
http://www.amazon.com/gp/product/B00...SIN=B000S1CEQ4
It's a higher quality switch, given that it allows component. But it runs $125.
or this:
Cablestogo 40446 HDMI Selector Switch (6-Port)
http://www.amazon.com/gp/product/B00...SIN=B001DFTH0A
Again, higher end, so $75 each.
Generally speaking, you're more likely to find switch boxes like this one, for under $20:
Sima SVS-14 4 Input Manual A/V Selector
http://www.amazon.com/gp/product/B00...SIN=B00005NCWK
The brands generally associated with these kinds of devices include Terk, Sima, Cablestogo, RCA and Philips.
What I do is fill up all available slots on the HDTV, as there are quite a few HDMI, component, composite and s-video available.
You NEVER want to capture video through a switch, due to the aforementioned noise-adding nature of switches. You should always connected devices on by one. Anything not essential should be unplugged from the TV/computer, possibly from the electrical. Again, power line noise is easy to generate.
