Never seen a one on my Samsung 61 inch LED RPTV and by BD55 using SD-DVD. Same is true for my Pioneer DV-610 and sd-dvd and my Samsung 61 inch LED RPTV. Do you have a sd-dvd that you use that shows them clearly on your monitor Winston?
"'Jaggies' is the informal name for artifacts in raster images, most frequently from aliasing, which in turn is often caused by non-linear mixing effects producing high-frequency components and/or missing or poor anti-aliasing filtering prior to sampling.
Jaggies are stairlike lines that appear where there should be smooth straight lines or curves. They can occur for a variety of reasons, the most common being that the output device (display monitor or printer) does not have enough resolution to portray a smooth line. In addition, jaggies often occur when a bit-mapped image is converted to a different resolution. This is one of the advantages that vector graphics has over bit-mapped graphics — the output looks the same regardless of the resolution of the output device. The effect of jaggies can be reduced somewhat by a graphics technique known as anti-aliasing. Anti-aliasing smooths out jagged lines by surrounding the jaggies with shaded pixels. This can be done in a computer or in a printer."
