Do the video filters dsize and scale now work with -ovc copy?

mencoder -ovc help

Available codecs:
    copy     - frame copy, without re-encoding. Doesn't work with filters.

That's why I never used them with copy.

I was having the same problem with a video, and this fixed the audio 
delay.  The muxrate fixed Too many audio packets...  You may have to 
increase the rate.

-ovc copy -oac copy -noskip -mc 0 -of mpeg -mpegopts 
format=mpeg2:muxrate=9095:tsaf
