Comment:

 I've been able to reproduce the problem by marking a bookmark when you see
 the man praying with a rosary.
 You then exit and come back.

 Log will show that audio is being opened with:
 (Video) already open.
 2010-09-13 14:54:18.201 AFD: Warning, audio codec 0x9133090 id(MP3) type
 (Audio) already open, leaving it alone.
 2010-09-13 14:54:18.201 AFD: codec MP3 has 0 channels
 2010-09-13 14:54:18.201 AFD: Audio Track #1 is A/V stream #1 and has 0
 channels in the English language(6647399).
 2010-09-13 14:54:18.201 AFD: Warning, audio codec 0x3a80070 id(MP3) type
 (Audio) already open, leaving it alone.
 2010-09-13 14:54:18.201 AFD: codec MP3 has 0 channels
 2010-09-13 14:54:18.201 AFD: Audio Track #2 is A/V stream #2 and has 0
 channels in the Dutch; Flemish language(6583668).
 2010-09-13 14:54:18.201 AFD: Trying to select audio track (w/lang)
 2010-09-13 14:54:18.201 AFD: Selected track 1: English MP0 ?ch (A/V Stream
 #1)
 2010-09-13 14:54:18.201 AFD: Initializing audio parms from audio track #1
 2010-09-13 14:54:18.201 AFD: Audio format changed
                         from id(NONE)     -1Hz -1ch -1bps     to id( MP3)
 0Hz  0ch 16bps

 So AFVD tries to open the audio card with 0Hz , 0 channels which is
 obviously not valid.

 Re-assigning to someone else, this is related to libavcodec usage in avfd.
 It is different to the issue of having an AC3 stream going 6->2->6->2
 etc...
