Hi -

	MPlayer says to notify the development team about unknown aspect_ratio
	information.   Here's the report ;)

	I used the 'mjpegtools' package to recode a vob from a DVD to VCD

		mpeg2dec -s -o YUV foo.vob | yuvscaler -O VCD \
			| mpeg2enc -h -4 1 -2 1 -f 1 -p -o foo.VCD

		mplayer foo.VCD

Detected MPEG-ES file format!
Detected unknown aspect_ratio_information in mpeg sequence header.
Please report the aspect value (6) along with the movie type (VGA,PAL,NTSC,SECAM) and the movie resolution (720x576,352x240,480x480,...) to the MPlayer developers, so that we can add support for it!
Assuming 1:1 aspect for now.
VIDEO:  MPEG1  352x240  (aspect 6)  29.97 fps  1440.0 kbps (180.0 kbyte/s)
[V] filefmt:1  fourcc:0x10000001  size:352x240  fps:29.97  ftime:=0.0334

	According to mpeg2enc aspect 6 is:

INFO: Aspect ratio code: 6 = 1:0.8437 (16:9 Anamorphic NTSC for 720x480/352x240 images)

	which makes sense - it is a widescreen (16:9) movie.  The resolution 
	is 352x240 (NTSC of course in the US).

	If you need more information let me know.
