I can't help there. There are several options in transcode that don't
work along with ffmpeg. That's a question for the transcode mailing
list, not here. Although, the "-R" option _might_ help.

Now that one I can help with... Create a file named "ffmpeg.cfg". Put
the following lines in it:
[mpeg2video]
aspect=4/3
That should take care of it. Read docs/export_ffmpeg.txt under the
transcode source directory for more.

I've seen this too, and just dismissed it. It doesn't make much
difference if mplayer can't detect the video bitrate.

Your audio-sync issues probably aren't caused by sox, or mp2enc, or
toolame. However, you could just leave-out the audio codec
all-together and convert the audio by-hand, with whichever tools you
prefer. I often use a command like this:
mplayer $INPUT -srate 48000 -ao pcm

Nope... In fact there doesn't seem to be any ways to modify toolame's
befault behavior other than setting bitrate. I actually had to edit
'export/export_toolame.c' just to force it to use psychoacoustic model
2.
