I noticed poor picture quality on a few stations, and found out these channels were being over-compressed. Let's not kid ourselves, compression is compression. ANY compression will produce artifacting, even a 25mb/s signal (although this would look quite good). Compressing HD channels down to ~12mb/s from 16mb/s is indeed noticable.

OTA HD signals look the best, but I'll at least agree to 2:1 with 256 QAM just so it doesn't ever get worse than this. NO MORE 3:1, PLEASE!!]]>Dec 17th 2007 1:39PM
