those XRGB units look like a pretty cool piece of equipment.
Sorry to divert the topic a bit but I just had a few questions about them,
these are about the cheap XRGB-1, I see the more expensive XRGB-3 has all sorts of connectors.
I see it has SCART, I'm in the US, so nothing has SCART, can one easily go from Component -> SCART? Say if I built a CMVS with a Neobitz with component output, could I feed that into an XRGB?
What outputs does it have? I see what looks like 2 db-15 plugs on the back, does it do Component, DVI? VGA?
You would feed RGBS directly to one of the RGB inputs with 160 ohm resistors in series on the red, green, and blue lines, or use the 220 ohm termination available on the front RGB input.
The XRGB-3 has two 15kHz RGB inputs - a 21 pin input on the front (not a "SCART" pinout), and a HDDB15 connector on the back (i.e. VGA/Analog connector). You do not need to convert RGB to component to use the XRGB-3. I've used my MVS with the XRGB-3 and it works great!
The XRGB-1, XRGB-2, and XRGB-2+ are line doublers only (15kHz to 31.5kHz). The XRGB-3 is a full scaler (in B0 mode) and line doubler (in B1 mode). B1 mode on the XRGB-3 behaves like a XRGB-2+. B0 mode provides pixel resizing to the selected output resolution. I primarily use the XRGB-3 in B0 mode with the output resolution set to 1920x1080.
Even using the best RGB to Component converter (FC-14), many HDTVs cannot handle 240p component signals. Panasonic PDPs flicker, and do all sorts of other things that makes low-res component unusable. My HDTV handles 240p via component correctly, but is on the soft side, so I've moved onto a XRGB-3.
BTW- Amazon Japan still sells the XRGB-3 brand new! The only issue is that Amazon will not ship the unit out of Japan, but a non-resident can still purchase! Hence, you can order these new, have them shipped to someone you know in JP, and have them ship it to you, or pickup during a trip there!
