i have a jvc gz hd7 and i just bought a imac. since my jvc saves the files under TOD and my imovie 09 doesnt support it i had to convert it using tipard hd converter and i converted it first to mp4 video and then hd mp4 and when i played it on imovie or quicktime i get alot of line on moving objects and dont know why this is happening. here is the link to the video on youtube so you guys could check it out.

the first clip in on mp4 and the second is on hd mp4
