get_iplayer is a perl script, so you can edit it in any plain old
text editor. After googling around on hydrogen audio for about
half an hour yesterday, I decided to upgrade to lame 3.98.2 (for
its improved vbr) and use these arguments: "-q 0 -Y -v".
So, I edited get_iplayer to replace this line:

$binopts->{lame} = '-f';

with this line:

$binopts->{lame} = '-q 0 -Y -v';

new versions of get_iplayer come out =constantly= so I wish
there was a way to store these options somewhere :)

Well, I'll keep uploading mp3s... it's going to be the
lingua franca of the audio world for some time to come.
(My Cowon D2+ doesn't support aac, and my personal
preference would be ogg... ;)

Does trimming the ends and saving as mp4 cause a re-encode?
Because if it doesn't re-encode, and if the results play
nicely with iTunes/iPods/etc, that would be very nice indeed...
