When I warped a mov file using the virtualdub frameserver method and GL_warp2avi, found that the video had not completed till the end. Digging in, found that the output frame rate was 25 fps, while the input file had 30 fps. Looks like the directshowsource avisynth method does not correctly report frame rate for some files? Manually setting the frame rate to 30 fps in virtualdub, then creating the frameserver signpost seems to solve the issue.
Edit: The problem seemed to be with ffmpeg reading the Sorenson SVQ3 video codec. Had to use Avidemux to transcode to AVC (x264) and then use directshowsource etc.
