I have problem burning video jerkness as DVD. For instance, I have 800 MB movie, when i use DVD author to authored it came out less than 800MB-400MB. When I check the thumbnail I drag to that frames and it stop and the rest behind it just white frames. I can't view it afterward. However, when I watch the movie using RealPlayer, there is a jerkness on that frame or missing block. I dont know what this problem call. All I know it jerking . Are there anyway I can fix this problem or burn the whole movie as DVD and able to watch it, like vcd or svcd able to burn and watch it.
