Koyote Free Video Converter V3.1.0.0

Hello,im starting with lightworks. Seams to be a realy cool software.I got the following problem. I want to import a film from my sony camera which deliveres.mts videos (HD). As lightworks doesn't import.mts I confert the video to.vob with the software Free Video Converter' V3.1.0.0.vob is in that case: MPEG-2; 1920x1080; 16:9; 25Fps; Bitrate:9000; Deinterlace or not.The video seems to be ok when i watch it on vlc. But when i import it in lightworks an place it on the timeline the video is only 11s long while the original video is 23s long!This is strange because the imported sound (AC3) which comes with the video has the right length.Could yo please help me? What is going wrong?Thanksdrewle.
