I am sharing something about this topic I know. A DVD audio track in Dolby 5.1 comprises of 6 channels namely Front-Left, Center, Front-Right, Rear-Left, Rear-Right. The vocal comes only through the center channel.
Using a software like DGIndex, you can extract the audio of the required sequence in AC3 format with all 6 channels intact. Now you need to downmix to MP3 format. For that BeSweet can be used. Now BeSweet has an option to control the Downmix Power Level. You can input the power level in dB for each channel separately. Now to eliminate the center channel, you can try a negative powerlevel like -50dB or something for center channel alone, while not touching the power level for other channels. Also you have other options like specifying the output bitrate. And when you click the "AC3 to MP3" button what you shud get is an MP3 file with center channel eliminated. I hope that was helpful.
