New submission from Steven Zakulec <spzaku...@gmail.com>: >From the uncommon audio codec list, the 2005_L23_CELTA__________1-Villarreal_____0___1-0_Baiano.avi file is MP1, and if you play it with FFplay the voices are distorted. If you play it with MPlayer and force libMAD, the voices sound normal.
