That card works fine, in fact its recommended by many vdr users. Here is the scoop.
The card does NOT do HDTV decoding in hardware. It will do it in software assuming the modulation is QPSK, (it does NOT support 8PSK commonly used for HDTV at least here) The card is used like a budget card if you are doing HDTV.
The "j2" mod on that board is done incorrectly. It does NOT have the proper circuitry to work "out of the box", (It does NOT do component, only RGB). It is NOT terminated properly. It does post a risk of damaging the card if things are incorrectly wired. Correctly wired and terminated the RGB out works excellent.
Any other questions?
I'm confused. I thought component video was RGB? s-video uses luminance and chrominance, component uses RGB - am I wrong?
Component video is "color difference", S video is very similar to component, as there is a Y(luminance) but there are 2 color signals instead of one (R and B), the "difference" between R and B, makes G. RGB contains much more video bandwidth then component video. Svideo cannot handle HDTV, Component and RGB can.
The SCART pinout says "RED/Chroma pin 15", "RED/Chroma GND pin 13", "Green pin 11", "Green GND pin 9", "Blue pin 7", "Blue GND pin 5".
How do you go about terminating the RBG from J2 properly? What can this be connected to?
Usually you need the filters and the termination resistors, and depending on where you live, RGB devices may or may not be common. (Think SCART)
So the tuner will tune QPSK HDTV channels, which can be recorded or displayed with vdr-xine or softdevice, but the MPEG decoder won't output them. What's the best setup to use this then? Do you run vdr-xine or softdevice all the time and ignore the FF bit - to support TV and HDTV? Or just start vdr-xine when you tune to an HD channel? What does the MPEG decoder output when tuned to HDTV? Is there a better FF HDTV card with component/s-video MPEG decoder?
I have 3 DVB-s cards in one machine, 1 is a FF, the other 2 are budget. I run in softmode using softdevice 100% of the time. Even though I don't receive and HDTV at all, using the output of a VGA card into a LCD projector produces a much better picture.
The advantage to the FF card, is that it will work in a slow computer as the card does all the work.
Displaying HDTV will need a powerful computer.
