    A while back I read a post about s video hookup vs composite on DBS hookup.Basically it delt with the possibility that better PQ can be had using composite due the the better comb filter in the TV than the DBS reciever.I have my stuff hooked up both ways,and just really cant tell a difference.Anyone else messed around with this?

    thanks

    There's no comb filter in the DBS box. Digital Satellite is broadcast as seperate chrominance (sp?) and luminance. It makes no sense to use composite if your TV has an S-Video input.

    Same thing here. I just upgraded my DSS last weekend and hooked it up with composite and there's about a 20-30% improvement. I have a New Hitichi HDTV that has 1080i.:b

    Some digital satellite systems include some analog source channels that do not have luminance and chrominance separated prior to transmission. Your satellite tuner box needs a comb filter to make good S-video from them. Some tuner boxes use a filter similar to that in a cheap composite to S-video converter rather than a comb filter. Here you might find that composite to the TV looks better.
