I am using the lastest binaries of mplayer and
mencoder for Windows.

I am trying to remove commercials from an mpeg2 file
using edl information created by Show Analyzer.

Here are the cli arguments that I am using:

"c:\Program Files\mplayer\mencoder" "test.mpg" -edl
"test.edl" -oac copy -ovc copy -of mpeg -o

Here is the edl file contents:

0	88.8555	0
266.333	400.834	0
746.18	895.696	0
1256.02	1430.26	0
1781.75	1978.61	0

And here is the mencoder process output:

The process seems to recognize the EDL actions, but
the final output only shows the first commercial

Your assistance is greatly appreciated.
