-This is help for those having trouble capturing audio with your Video Capture Card [VCC]
--
-The issue is related to virtually every video capture card on the market. It is a VIDEO CAPTURE CARD, and does not capture audio. This is the reason you'll get from every tech guy you speak with, so don't pay money or waste time. The sad part is it's true. An audio capture card is your sound card, which obviously doesn't capture video. They are 2 seperate things.
-Fortunately, this will help you capture video and audio with your computer using a Video Capture Card [VCC] and Sound Card or motherboard's integrated sound [ISC] (my acronym for Integrated/Sound Card)
--
-I'm not exactly sure why, but audio and video cannot be recorded together digitally. They are coded separately, though integrated together for the playback process. (part of the reason why some people get audio out of sync). It may be because the actual digital frequencies for audio and video may be identical and would cause some sort of distortion or confusion for the processing unit if they are read together. This is only my theory. This is just technical crap for the diehard A/V junkie. From analog devices (IE: VCR, camcorder, etc.) you have to separate the signals through what is known as 'composite ports'; the RCA Jacks. A digital device with composite ports can be substituted.
--
-This process is for linking one analog device to your VCC & ISC. Here is what you'll need and are pretty cheap & can be found at most stores (IE: BestBuy, Wal-Mart, Target, CompUSA, Circuit City, etc.)
*RCA Stereo Audio cable
*RCA Video cable
*RCA to Stereo HeadPhone Jack cable
*2 RCA Y-Jacks (2-female to 1-Male)
*Audio Ground Loop Filter [GLF] (not required)
--
-Lets first begin with the analog device. Connect the video RCA cord (usually yellow) directly to the analog device. Connect the other end to the video input of your VCC video port or cable.
-If using a GLF, connect it to the corresponding audio output ports on the analog device. Right (usually red) to Right, Left (usually White) to left
-Connect a Y-Jack to the Right audio output and the other Y-Jack to the Left audio output of the GLF. If not using a GLF, connect to the corresponding ports on the analog device.
-Connect on end of the RCA Stereo cable to the Y-Jacks. Each Y-Jack should now have one female side not connected.
-Connect the other end of the RCA Stereo cable to the VCC audio ports or cable.
-Using the RCA to HeadPhone Jack cable, connect the RCA jacks to the remaining unconnected Y-Jack ports.
-Plug the HeadPhone Jack into your ISC 'LINE IN' port.

IMPORTANT
************
In your Vomlume Controls, only 4 items should not be muted when recording: Master Volume; LINE IN; WAV; and the device your video card is connected to (IE: AUX, CD-IN, etc.; whichever the video card is connected) All others MUST be muted.
