FFmpeg input time offset help

[kenmasters1976]

I have some AVI videos I captured with VirtualDub and I'm trying to convert them to MPEG2 with FFmpeg for later use with dvdauthor.

I've done this before, but now I'm trying to apply an offset to the input video and I've tried the -ss and -itsoffset but the offset only is applied to the video stream. How can I force the offset to be applied to the audio stream as well?.

I'm using the latest automated FFmpeg binary for Windows and Windows XP SP2.

Thanks.
