The resulting file is http://dl.dropbox.com/u/43104344/out_ff.mpg
It likely plays well in mplayer2.
Playing in ffplay or transcoding resulting file to another codecs with ffmpeg
result in warnings
[pcm_s16be @ 0x844e460] invalid PCM packet
(in ffplay, the noise is heard).

The same happens with -f mpeg. Only bufi= numbers differ a bit.

ffplay surely supports playback of this codec in this format. Example of
playable file is http://streams.videolan.org/samples/MPEG-VOB/LPCM/Fever.vob

Please add ffmpeg -i Fever.vob output.

Muxing and remuxing works now but WMP does not play the resulting files (it does player Fever.vob if it is renamed to Fever.mpg).

Keywords:	mpegps added; mpeg removed

This was fixed (at least) over a year ago, I originally didn't test with -f dvd (or -f vob).
