When I have a recording that starts before the channel is fully active I
can usually use dd to recover it.
------------
cd <recordings_directory>
mv foo.mpg foo.mpg0
dd bs=1M skip=50 count=40 if=foo.mpg0 of=foo.mpg
View the recording. If it's ok omit the 'count'; if not try a different
value for 'skip'.
Rebuild the seektable. The simplest way is probably just to transcode
the recording.
rm foo.mpg0
cd
