miniDVD with audio only

[ghuul]

I'm trying to make MiniDVD with AC3 music. I'm able to create disc with MPEG still image and AC3 stream. It works, but it is not possible to rewind, because it acts like photo gallery with background music. I can only pause or play music. And my questions are :
1) is there some way how to edit/manage .ifo files so I can use rewind (eg. fake duration of video stream) ?
2) if not, is there some way how to create MPEG2 video stream with smallest possible size ? i.e. generate some black mpeg2 video or video with only one I frame (or something like that).
3) is there some other way how to do that ?

Thanks
