My Input File to version 3.

(1) .MKV File
(2) Video is H264, 1260 x 544
(3) Audio is AC3, 5.1, 48000Hz, 640Kbps

After NTSC DVD conversion is complete, the audio remains AC3/5.1 @ 640Kbps and I think it should be 448Kbps to be DVD compliant. The 640Kbps audio is from Blu-Ray, and unless I am wrong, it should be a lower bit rate for standard DVD.

I do not see a transcoding down of the audio from the source. It looks like a pure copy of the source audio.

Is this correct?
