sed command in perl script
What is wrong with this line in a perl script?

Code:
 
$amc_data = `sed -n '/\[Amc\]/,/\[\/Amc\]/p' "$config_file"`

I ran the above from command line and it works fine from unix command prompt.
The code should produce output between the [Amc] and [/Amc] tags.

The config_file is as follows:

Code:
 
[Amc]
Sun     0000-2359
Mon     0000-0859;1830-2359

mlib_videocoloryuv444seq_to_argbint

mlib_VideoColorYUV444seq_to_ARGBint(3MLIB)		    mediaLib Library Functions			mlib_VideoColorYUV444seq_to_ARGBint(3MLIB)

NAME

       mlib_VideoColorYUV444seq_to_ARGBint - color convert YUV sequential to ARGB interleaved

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       void mlib_VideoColorYUV444seq_to_ARGBint(mlib_u32 *ARGB, const mlib_u8 *Y,
	    const mlib_u8 *U, const mlib_u8 *V, const mlib_u8 *A_array,
	    mlib_u8 A_const, mlib_s32 w, mlib_s32 h, mlib_s32 dlb, mlib_s32 slb);

DESCRIPTION

       The  Y,	U,  V  pixel  streams  are converted into an ARGB pixel stream. All pixel components are 8-bit unsigned integers. All buffers have
       dimensions w and h.

       The alpha values for this function work in the following fashion:

	   o	  If A_array pointer is not NULL, the values are taken from there. It has to have the same dimensions as the Y buffer.

	   o	  If A_array pointer is NULL, the alpha values for every pixel are set to A_const.

       The following equation is used:

	 |R|   |1.1644	0.0000	1.5966|   [|Y|	 | 16.0000|]
	 |G| = |1.1644 -0.3920 -0.8132| * [|U| - |128.0000|]
	 |B|   |1.1644	2.0184	0.0000|   [|V|	 |128.0000|]

PARAMETERS

       The function takes the following arguments:

       ARGB	  Pointer to output buffer.

       Y	  Pointer to Y input buffer.

       U	  Pointer to U input buffer.

       V	  Pointer to V input buffer.

       A_array	  Array of alpha values.

       A_const	  Constant alpha value.

       w	  Image width in pixels.

       h	  Image height in lines.

       dlb	  Linebytes for output buffer.

       slb	  Linebytes for input buffers.

RETURN VALUES

       None.
