Don't worry, you are not having this problem due to being in the PAL format. Your problem stems from the interlaced scanned TV that is displaying the hard edged horizontal lines in your graphics. When the very edge of the horizontal line goes from a dark (usually black) line to the light (usually white background) the edge of this line can't decide whether to jump to the odd or even field. To prove this to yourself just select the odd or even field display with your PAR output. This in itself may be the solution you need to display your stills, ie. use field odd or even display rather than frame display. If this doesn't work, I have had some success using blur in photoshop to create a gradient edge to horizontal lines in a sharp graphic such as those created with corel draw. This will degrade the sharpness of the image but it may be necessary to get around the old plucked guitar string look to those lines. Just remember it is usually not the thickness of those lines but the sharpness of the edge of the line and it's placement in reference to the location of the odd or even field scan line that causes this problem.
