ps3 mkv to mp4

Stick this in ~/.mplayer/mencoder.conf

[PS3_MKV]
oac=lavc=yes
lavcopts=vglobal=1:acodec=aac
af=volume=10
ovc=copy=yes
of=lavf=yes
lavfopts=format=mp4
forcedsubsonly=yes


Then do:
mencoder -profile PS3_MKV input.mkv -o output.mp4

Transcodes the audio, but that's very quick. Could not find a way to copy audio that worked. Tried the fafmttag values in my copy of codecs.conf:
format 0xff
format 0x706D
format 0x4143 ; aac in asf
format 0xA106 ; aac in avi
format 0xAAC0
