iphone video (h.264, aac, .mov) sound issues

I'm trying to edit this clip captured on an ipod touch 4g (same format as iphone) with free software (avisynth and virtualdubmod). This is on an XP SP3 machine with ffdshow-tryout beta 7 (decoding aac with libfaad2). I tried opening the original file with no luck, so I used Mp4Cam2AVI to convert to avi and tried that too, also with no luck. Here's my script with comments:
Code:
#directshowsource("IMG_0078.mov")  # no audio - stream list empty
#directshowsource("IMG_0078.avi")  # out of sync
#ffmpegsource2("IMG_0078.mov")     # no audio - stream list empty
#ffmpegsource2("IMG_0078.avi")     # no audio - stream list empty
#ffvideosource("IMG_0078.mov")     # no audio - stream list empty
#ffvideosource("IMG_0078.avi")     # no audio - stream list empty
#avisource("IMG_0078.avi")         # w/o aacacm installed - "No compatible ACM codec to decode 0x00FF audio stream to PCM"
                                   # with aacacm installed - "ACM reported error on audio decompress"
Can someone please explain to me (like you would to a slow child please) how to get this working with free software?

ffmpegsource2 and ffvideosource both ignore audio by default - you need to add atrack=-1.

If you still have problems after that, what does MediaInfo (use search if you don't know what that is) say about your audio track? Post a text listing here.

That did the trick (I know, I know - RTM, right). Thank you for your help.
