Plug an adaptor into that, on top of which you plug a S-Video cable then hook its other end into the Dazzle. It supports SCART pass-through (which I didn't use in the end), computes the S-Video signal using the input RGB signal, hooks the result (as well as the untouched audio signals) into a SCART output socket. This device must be powered through an adaptor while it's in use.
I bought a SCART RGB to S-Video converter and got it shipped from the UK. To get true S-Video quality, I needed more than just adapters: an expensive device. But, it turns out that PAL Wiis do NOT output a S-Video signal they output RGB instead, which happened to be what I was using in the first place (through a separately-bought Wii SCART cable) when I played on a TV set. what a hack) Before I could figure out why, I decided to fall back to Composite quality, which made me buy a third RCA cable. (Basically, the S-Video signal was basically a mash-up of the Composite signal hooked up twice as the two inputs.
Unfortunately, my S-Video quality looked REALLY poor, as if "oversaturated" portions of the image turned into grey. And bingo, I can properly use DirectShow streaming software! So I bought an adapter cable that converts 2×RCA(audio) to 3.5-jack, and used it to plug audio to the "Line In" jack socket of my PC.
Their drivers do NOT expose audio input to DirectShow, unlike video input.
Which leads to another problem : grabbing Dazzle's audio input in software other than Pinnacle's (which are crippled, especially Instant DVD Recorder software). It takes up quite a lot of space for legacy quality, which was a reason for me to steer away from it. I could finally begin recording with Instant DVD Recorder which saves the footage in DVD format onto a hard drive (or to DVD as the name says). The first problem I had was the lack of colourful PAL60 video, worked around with the AMCap trick. Under the assumption that PAL Wiis are able to output a S-Video signal (better-looking than Composite), I bought 2 RCA audio cables, a S-Video cable, and a SCART adapter to hook it all together to my Dazzle. How was it back when you started using the Dazzle?.The following is the long answer to the question: (TODO)
