[Lame-dev] CBR/ABR quality regressions for q0, q1, q2 and q3

[Tobias D. <tob...@gm...>]

Yeah I got that, my reply was ambiguously formulated, sorry.

I think the man page should mention something like:

"When in vbr mode, using -q0, -q1, -q2, -q3, -q4 or no -q at all will
result in the same settings and hence, identical files."

Now back to some actual problems, sorry for the spam!
