capture resolution???

[OmegaMaster]

i use vcr and as i read in the guides for captureing, the higher the resolution the better the stuff, for filters and so on...
so i captured at 720x576 (pal_b) and a threshold width 288, but i get a very bad result screenshot - huffyuv720x576-288 (http://www.thomastaucher.at.tt/huffyuv720x576-288.JPG)
so i tried with a threshold of 576 but nothing better screenshot - huffyuv720x576-576 (http://www.thomastaucher.at.tt/huffyuv720x576-576.JPG)
so i captured with a resolution of 320x240 and get a better result screenshot - huffyuv320x240-288 (http://www.thomastaucher.at.tt/huffyuv320x240-288.JPG), but it isn't really sharp.

is this normal or is something wrong.

what you see is called interlaced video, and it's perfectly normal.
you may want to read this (http://www.doom9.org/ivtc-tut.htm) guide. i'm not striking you since you're new here. but you should have read the capture guides more carefully.

sometimes, each image is actually composed of 2 images interlaced (weaved) together. this mostely happens on live programs, and not on films (movies). when you capture at the lower resolution, you only get one of these images, and there is no "comb" effect. you can capture at high resolution, and then de-interlace later.
