According to the F.A.Q. 640x464 is ok for PAL (verified on my personal camcorder). I'll have to investigate the proper resizing values for NTSC, they might be different, but because of the rounding due to the mod 16 height constraint it may turn out that the same resolution is recommended for NTSC. Don't know yet, but I'll extend the F.A.Q. as soon as I know. Be aware of the fact that not all monitor resolutions have a 1:1 aspect ratio. E.g. 1280x1024 monitor resolution is 5:4, not 4:3, thus the pixel aspect ratio is different (because the monitor size stays the same, of course). If you use this monitor resolution, switch to 1024x768 and see if the problem's gone. I highly recommend to assume 1:1 pixel aspect ratio in order to calculate the resizing. If you need to display the video on device having a different pixel aspect ratio (e.g. a TV set, or a computer monitor with a strange resolution), then let the player do the final resizing. bb
