[MEncoder-users] DVD to VCD Convertion

[Ron Wills]

Hello All

  I've got a quick question. I'm converting a couple of DVD's to VCD for 
my laptop, which I have been successful doing. I've been able to reduce 
the bitrate for the audio to improve the video quality, but I can't seem 
to get the stereo channels reduced to mono. I've tried the -lavcopts 
amode=0 and the -channels 1 options. But when I play back the mpg 
mplayer says:

AUDIO: 44100 Hz, 2 ch, 16 bit (0x10), ratio: 16000->176400 (128.0 kbit)

Checking audio filter chain for 44100Hz/2ch/16bit -> 44100Hz/2ch/16bit...
AF_pre: af format: 2 bps, 2 ch, 44100 hz, little endian signed int
AF_pre: 44100Hz 2ch Signed 16-bit (Little-Endian)

  I could be reading the wrong output from mplayer, but everything 
concerning the audio is saying 2 ch which I'm assuming is 2 channel 
stereo. Currently the audio channel in the VCD is taking about 120Mb in 
stereo I should be able just about half this with a single mono channel 
giving me 640Mb for the video where the quality drop is most apparent.

  This is not urgent, but would like to get some insight into this and 
try to reduce the amount of flicker in the VCDs. Thanks for the help in 
advance.
