Avi Movie Coversion Problem with 2 languageAudio Soundtracks

HI I was wondering if anyone clever enough can solve this one, I have downloaded a classic movie in avi format, but it came with two Audio soundtracks one spanish and the other english, on my Nero showtime i can watch this film and change the soundtrack from spanish Audio1 to english Audio2, however when i go to convert it to a dvd file so i can burn it to watch on my dvd player it will only convert it with the spanish language Audio1 soundtrack, I can't get it to convert or find the english Audio2 language soundtrack most frustrating, only Nero showtime will seperate them,but of course can't convert them, does anyone have any solutions to overcome this problem, I have tried software converters like winavi converter, intervideo windvd creater, superdvd creater, but none will reconise the English Audio2 track like Neroshowtime, and yes I have tried Nero's other dvd programs and they don't reconise the Audio2 track either, unless I'm doing something wrong, please advice and thank you for your time.
