Typical responses about this "common problem" are usually based on using poor source material and/or comparisons of widely disparate quality compoents. I think you fall into the latter category.
Perhaps the OP should try a hi-rez quality DVD with his current setup in order to see if the problems are not inherent in his equipment. If so, swapping the DVD drive for a BD wouldn't be progress.
