MP4 to divx avi

[Maritimer]

Is there an easy and fast way to take my MP4 and convert it to a divx avi and keep the quality from the MP4, so that I use on my usb stick for stand alone DVD/Divx player?

I use FFmpeg for that: ffmpeg -i input.mp4 -vcodec mpeg4 -vtag xvid -qscale 3.0 -flags +aic+mv4 -trellis 1 -mbd 2 -cmp 2 -subcmp 2 -g 250 -me_range 1023 -acodec libmp3lame -ab 192kb -ar 44100 -ac 2 output.avi

If the resolution is higher than your standalone will play (HD), add "-s 640x360" to resize it (16x9). If you really want identical quality, use -sameq instead of "-qscale 3.0," but -sameq is pretty slow.

EDIT: I figured out why -sameq was so slow for me - all the other encoding options should not be used with that option, it seems. When only -sameq use used, and the other flags and options are omitted, transcoding is fast. The resulting bitrate seems unnecessarily high to me, though.
