@Dave865 I would used the command line program ffmpeg to actually chop
and either vlc or mplayer to find the splitting points. ffmpeg -ss
<start> -i <input file> -codec copy -t <duration> <output-file>where
<start> and <duration> can be in seconds or hh:mm:ss and the output
file and input file have the same type (e.g. .mkv, .mp4, etc.).  The
'-codec copy' part avoids transcoding (making the creation of the
output MUCH faster) at the risk of making the times more approximate,
so make sure to play back the result (just the beginning and the end)
to make sure it is acceptible. Leave it out if you need to change
video formats, e.g. go from .mkv to .mp4.You can adjust the start time
and/or the duration up or down a little and try the ffmpeg command
again with the adjusted values to fix an unacceptible output.
