DVD Transfer & Advanced Audio Cleanup -- 2

I have a 30–60-minute home video in MP4 format that I need moved onto a standard DVD-R. The audio track requires thorough enhancement: increase overall audio volume, remove wind and hiss, and isolate/enhance male and female voices for clarity as much as possible...
