I'm trying to find the best 640x480 interlaced NTSC ModeLine. This one looks good to me: ModeLine "ATSC-480-59.94i" 11.958 640 664 736 760 480 484 492 525 Interlace However, running X gives this error: (II) MGA(1): Not using mode "ATSC-480-59.94i" (bad mode clock/interlace/doublescan) What NTSC ModeLine works for you? Thanks, Shaun
