Ok, here's the promissed patch :)
If mplayer is available, it will use it for all media files. If the file is an
mp3 and pymad is installed it will get the length reported by pymad and
compare it to the length from mplayer and use the longer of the two (this
works great btw). And of course, worst case eyed3 is still available if all
else fails.
Oh and btw, about Cory Doctorow's podcasts. The mp3s are borked, all the media
players I tried them with gave different play times. Pymad gets close to the
right time but is off by ~10sec. Email Cory and tell him to use a better mp3
encoder (he still reads all his emails right?).
Enjoy,
nick
