Hi all, just want to get some help. I connected my Sky Decorder to my PC TV tuner card via an RCA cable, the sound is perfect but the video looks quite washed out, it's almost like watching black and white tv with a tinge of purple. Any idea what's the problem or a possible solution?

(Also tried the SCART cable to my TV tuner but the same issue)

Many Thanks

Checked that the output options on the sky box are set to composite? What you are seeing would happen if you have it set to svideo etc since there would be no chroma signal except for what you get from crosstalk etc.

Secondly check the input signal is set to PAL on the capture card software.

If possible, use s-video (small 4-pin connector) otherwise you are loosing quality quite a bit. S-video is in the format that the video is processed, composite is just s-video modulated into 1 signal which then gets de-modulated in the tuner card. The capture chip processes only s-video.

Thanks heaps for all of the above suggestions, will definitely give them a go. Just want to clarify one thing, if I try connecting to the tv tuner with S-video, does it mean I need to have a cable with one end of either RCA or SCART (the only connectors available on the back of the decoder) and the other end of S-Video? Apologize if that was a silly question :)

If there is s-video on the back of the box then s-video to s-video is preferred, but I believe SCART to s-video also works. Depending on which SCART connector, you have to enable the appropriate s-video output. Sorry, don't have the same box as yours so can't step you through it. Mine only has 2x SCART connectors.
