The problem is the source file, have 5 channels instead 6 like standard 5.1 (3/2.1). Then the automatic downmix to 2 channels don't work, and Lame don't accept 5 channels.

Without a sample I don't know if your source is a 5.0 (3/2.0) or 4.1 (2/2.1 or 3/1.1).

A workaround may be use an .avs file with only this line:
NicAc3Source("I:\Naukar Biwi Ka\VTS_01_1 T01 3_2ch 448Kbps DELAY 0ms.ac3",2)

Then the downmix is made internally by NicAudio (only dpl is allowed) and the output is always 2 channels.

Open the .avs with meGUI, instead the ac3, and encode (Check the 'Increase Volume automatically', always recommended when Downmix).
