Thanks everybody for the answers... as a quicky I'll give bob a go, then I'll build the RGB cable it seems the only way to get the picture I really want (given my lowly P3).<br>(Pity I wanted to be able to use a composite vid/s-video input to the telly as the RGB is hogged by the cable box itself and needs to be manually switched over. Got to keep the WAF up ;-)!!!!).

<br><br>The pedantic answer is that it's actually doing both, but I don't<br>think that's really your issue :)<br><br>Your number one problem is s-video. It's been a long time since I used<br>it in anger but I never had a good quality picture using s-video

<br>converter is definitely the way to go. You'll notice an immediate<br>improvement in picture quality if you get it working correctly (I've<br>been playing with scart input to my lcd and crt tv's today). I'd
<br>probably go as far as to say that it's the best picture quality you'll<br>get for standard definition PAL - i.e. if you can get it working<br>well, it will match the quality from stb's, dvd players etc.<br>
<br>>i.e. is the NVidia TV-Out doing something<br>> to the timing...e.g. insisting on using 60hz without telling me thus<br>> throwing out the timings, or maybe even forcibly de-interlacing the picture?<br><br>Probably the latter...
