I download music clips of youtube on a regular basics. The problem is that most of them are not great quality. I know that when there uploaded there converted to Flash so when i download i encoded them to mpg format using Xilisoft Video Converter. But the program does not have any good features to improve the video quality of them. Which programs would be the best to improve the quality of the music clips? I even use Power Director 6 but it make no difference. Thanks.
