unplug the yellow video cable that's going into the card, and plug it into a monitor to make sure the picture has color. if so, the card or drivers are bad. if the picture still doesn't have color, then i would ask if you're using an s-vhs vcr, that has an s-video output, and an adaptor to convert s-video to composite video (the yellow rca cable). in s-video, one of the wire pairs is for luminance, and the other for chrominance (color). if the chrominance pair is broken somewhere along the way, all you'll get is a black and white picture.
i had a similar problem i was using rca cables to record programs from sat tv and only had b/w kept the rca for sound(rca to line in connector) and switched to s-video for picture problem solved works great now
it is currently set at ntsc m. the only other ntsc option is mj. what do those settigns mean?
NTSC M is North American NTSC, with .75 IRE black setup. NTSC MJ is Japanese NTSC with 0 IRE Black, also used for DVD. There is also a verison of NTSC in Brazil which uses European scan rates of 625 lines at 50hz, a bad system. For DVD authoring you'd probably be best off using NTSC MJ with its DVD conformation.
If i purchased another pcie card say, 6800gt, or w/e with a svideo tvout will i be able to use it to capture? or is my x800xt a special case?
Probably the best consumer capture card is the ATI Theatre 550 Pro (and its Sapphire and Tul etc. rebadges.) It has an excellent comb filter and near-perfect levels at default. There's also the newer Theatre 650 but there seem to be some issues with that chipset. You never get the best capture facilities in a video (out) card, though the high-end Nvidias are not bad, they don't have that great comb filter though.
