dont know if this could be any use to you... theres some software called MEDIABOX EDITOR STUDIO, you inport you channel list, make any changes and then export it, and one the options allows to exports it as an ABS file...... the softwares free but i cant remember where i downloaded it from, but im sure a google search will bring it up........
not sure if it will be of any use to you, but might be worth a try.
