    Hi,

    Ive got a problem with drifting lines on my DVD picture. Ive had alot of success cleaning up my audio sound with isolators, so was wondering if there was such a device for video?

    My dvd connects via a s-video cable. Its this connection I want to break with an isolator.

    Anybody know of anything thats not too expensive?

    thanks

    Quite a few AV signal distribution solution manufacturers provide video ground loop isolators - though they are quiet pricey as they tend to be aimed at the Broadcast market.

    When we've had problems in the past we've supplied the Extron GLI 2000 (2BNC) - though with an SRP of near £340.00 its not for everyone.

    This unit has BNC ins and outs so you'll also require a couple of S-Video to Two BNC adapters (approx £15 each).

    See http://www.extron.com/product/product.asp?id=gli2000

    Best regards

    Joe

    thanks Joe, but thats too expensive for me.
    That device costs more than my whole home cinema system!

    I was looking for something a bit cheaper and simpler to be honest. I managed to get an isolator for my audio that did an excellent job for under £25.
    I assumed I would find a simpilar type device for s-video, but it looks like i might have a challange on my hands!

    If your £25.00 solution goes 'in-line' with your audio cables (signal in > signal out) then you could try two of them along with a couple S-Video to 2BNC or 2RCA cables on your video line; though it may simply kill the video signal.

    Best regards

    good point Joe. I can try that with the isolator i have already.
    Still, it sounds a bit of a botch!

    Ill keep my eyes open for a more specific device for the minute. Im still open to suggestions.
