Oh, that... Did you get this -0.3 from playing DVDs? Have you tried to
play this DVD using -vo xv or -vo x11? If the delay was same, then
there is unresolved issue of proper a/v delay for DVD. I have to play
most of my DVDs with -delay -0.25[1].

PS. In cotrary to popular belief it's not dialogs that let you watch
accuratelly for a/v synch, it's gunshots, punches, explosions etc.

PPS. I've just done encoding of several seasons of Buffy and it apeared
that while I was playing it from DVD I had to add -delay -0.25. But when
I reencoded this to AVI and OGM with AC3 and Vorbis sound than I had to
use no offset for audio to get correct a/v sync.

[1] better than -0.3 since 0.08 mismatch is invisible for human, and the
 actual offset is somewhere between 0.2 and 0.3, hence 0.25
