Movie Maker will not display any video shorter than 1000 KB's. I have several videos to put together, they were all recorded at the same time, on the same camera, with the same card. They were all downloaded onto my computer at the same time. I can't see any difference in any of these video clips except the short length of those that will not display. ( Triangle with "error" and a black screen playback, but only on the too-short clips.) Can this be corrected? Thanks for any help, I cannot re-take these shots!
