This error is unrelated to the previous one and it won't affect the current encoding.
Please run:
yuvscaler </dev/null 2>&1
and post the output.

Ok, the trouble you had are due to the fact that input.mpg does not have an
audio stream. Only video. Or at least mplayer is not able to identify the audio
stream. 
Does "mplayer input.mpg" play with audio or not?

If the source does not have audio, the proper solution in your case is to use 
-encode 0:2:2.
I will fix encode2mpeg to output such message in case of source without audio.
