I had this problem and found it was due to the version of ffmpeg.exe
being used.
I "downgraded" to this one:
FFmpeg version SVN-r22140-Sherpya, Copyright (c) 2000-2010 the FFmpeg
developers
built on Mar 2 2010 03:26:44 with gcc 4.2.5 20080919 (prerelease)
[Sherpya]
libavutil 50. 9. 0 / 50. 9. 0
libavcodec 52.55. 0 / 52.55. 0
libavformat 52.54. 0 / 52.54. 0
libavdevice 52. 2. 0 / 52. 2. 0
libavfilter 1.17. 0 / 1.17. 0
libswscale 0.10. 0 / 0.10. 0
libpostproc 51. 2. 0 / 51. 2. 0
Which fixes the problem (doesn't have the bug).
IRC the probliem is that newer versions of ffmpeg produce files where
the audio bit rate gets encoded incorrectly and confuses the PS3 into
not playing the file at the correct speed.
You can extract and re-encoding the sound track with the correct
parameters and it fixes the problem on existing files. But downgrading
to that older version of ffmpeg fixes the problem on new downloads.
I don't know if the latest version ffmpeg has this problem fixed, I've
not tried it out as I know the older one works fine.
If you can't get hold of the older version let me know and I'll put it
somewhere you can download it.

Hi there. I have found out about the FFMPEG problem with watching
get_iplayer MP4s on a PS3 (video plays fast and with no sound). I
have got a problem in that I upgraded latest get_iplayer and forgot to
roll back the FFMPEG version.
1. Is there anyway I can tell which video files are affected (without
playing them)
2. Is there anyway I can "convert" the files to be playable?
Any help much appreciated.
