I have seen a lot of people complaining about burning disks : low quality,not being able to burn HD video in normal disks (4.7 GB),frames of video not moving smoothly etc. I had these problems until I found a software that was really fast,burning a movie of 90 min in less than half of hour.Also I was able to burn HD movies in normal disks without any visible quality loss.What I see amazing in this software is that you can reduce the quality of audio to improve the quality of video.If you don't want to make wrong calculations you can use smart fit,which automatically fits the video in DVD without leaving any free MB in the DVD (nothing is wasted). This software is called POWER DIRECTOR (a cyberlink software).
