vpass=1 isn't the default, zero is.
vpass=1 means the first pass in a 2-pass session.
vpass=0 means 1-pass mode. This is probably what you want.

Heh! "-oac copy" ??? I bet that's the problem ! You're recording in
PCM or whatever gives you your TV card, but certainly not in mp3 :)

Use "-oac mp3lame -lameopts vbr=3:br=128:aq=0" or something like that.
