This kit consists of a Scart to RCA+SVHS (S-video) adapter, an SVHS cable and an RCA to 3.5mm stereo audio cable. The adapter is switchable for input or output. (Scart doesn't allow bi-directional SVHS.)
The adapter looks cheap - which it was so I can't complain. It works but I don't think it'll stand up to hard use. Best to fit once and forget.
A good SVHS cable should have two independently screened cables in it: one each for luma and chroma. This one looks like it's multi-core overall screened, just like most cheap (and some not so cheap) Scart cables. I wasn't about to cut it open to find out so I did some rough capacitance measurements: 480pF core to screen and 460pF core to core. The symmetry is enough to tell me that it's four core with a single screen. With a 75 ohm load on each end the cross coupling will become significant at about 9MHz. I can live with that but I wouldn't want to try the 10 metre version of this cable!
The stereo audio cable is of somewhat better dquality than the rest though I still wouldn't subject it to too much hard use.
Not having a PC card with SVHS, I tested the video side on an HDR-to-TV link, using a second, high-grade Scart adapter and separate RCA leads for the audio.
My first attempt produced only monochrome but a little jiggling of the SVHS plug in my old adapter sorted that. The first test was with live digital TV from the HD recorder's tuner, It was a studio broadcast with a lurid red wall in the background. I thought TV producers avoided such troublesome decor but it was a good test because the red flared abominably. This was significantly reduced when I moved the new adapter from the DVD end to the TV end of the cable so it wasn't all down to sloppy TV production. (A quick check with an RGB connection reduced the flare a bit more but some remained.) 'Normal' video is acceptable; certainly better than CVBS.
Verdict: This is a cheap kit which does as much as you can expect for £2-99p. Handle the plugs carefully, don't expect high grade video and avoid the longer versions.
