Could I maybe use component video cables to reduce the artifacts? Im currently using an s-video between the cable box and TV.

Hi neighbor,
You should use either component cables, DVI or HDMI to get the HD display. I'd leave the s-video hooked up and add the HD connection as the s-video can actually look better on SD than the HD connection sometimes.
Yes it is digital cable that is causing the poor picture. The original material is compressed at the source and then decompressed by the cable box. HD material with its greater data will show decompression artifacts much less than the SD material due to the greater bandwidth alloted to HD channels. Here is an example of decompression artifacts on the left.
When blown up on a 50" display the noise of decompression as shown on the left between the SAT-L and DVD-L graphics will be exagerated on your display as opposed to the uncompressed example on the right. If you view an OTA digital signal from one of our local channels, they do the upscaling at the station and then merge it into the 16:9 frame and you will see the SD is about as good as a DVD. You need OTA unfortunately as the cable HD local channels are not quite as good due to compression and decompression of the cable signals, but they will be better than the other SD only channels.
Bottom line is there is very little you will be able to do about the poor picture. I have a 27" TV to watch SD myself.
