long audio track w/o video ?

In our DVD we have a long audio track more than an hour which we would like to add w/o any video . in the main menu we need to have a button..which should ( after selecting) play the lengthy audio w/o any video . may be we can have a picture which will be "there" till the audio plays . is there any proper method for doing this . and is there any way to have chatper mark for the same audio so that viewer can JUMP from one section to another with remote forward or backward.
thanks a ton
