As the player is Java, it works best on a Windows box (with JIT) or a very fast CPU. > as you'll notice from our webcam results in some image stability > problems. I noticed this myself too. Unfortunatly I do not have a fix yet. Best option is to limit grab sizes to less than half the TV resolution. For PAL, grab images less than 288 pixels high. For NTSC grab images less than 240 pixels high. This removes the interlacing (jagged edges) problems.
