The codec is apparently avc1 and ffdshow does pop into the Task Bar when the file is opened, but still only audio. I would like an AVI format as well to keep on my media player.
Strange that you can't playback the AVI, as h264 for video is quite
common these days.
Especially, if you've been able to playback the .mov before. hm...
Which player are you using?

I'm not 100% sure, but I think the default for "-target pal-dvd" is to
use 4:3.
Quoting a webpage I've just found [1], you might be able to use the
argument "-aspect 16:9" in your case:

ffmpeg -i in.mov -target pal-dvd -aspect 16:9 out.mpg

As you have to convert from h264 to MPEG (lossy) for using it in a DVD
player, there is no way of not losing "some" quality. However, the
higher the bitrate-value you choose for encoding the MPEG, the better
the quality.
