TEST.HDTV.XviD.avi: RIFF (little-endian) data, AVI, 624 x 352, 23.98 fps, video: XviD, audio: MPEG-1 Layer 3 (stereo, 48000 Hz)
encode script example:
$ cat testscript.sh
#!/bin/sh
ffmpeg -y -i $1 -acodec libfaac -ab 160k -s 720x480 -aspect 16:9 -vcodec libx264 -b 500k \

-keyint_min 25 -rc_eq 'blurCplx^(1-qComp)' -sc_threshold 40 -me_range 12 -i_qfactor 0.71 \
-directpred 3 outputTEST.mp4
exit
syntax:
./testscript.sh TEST.HDTV.XviD.avi
720x480 works like a charm...wish I could say the same for 848x480 
Tried a few variations, unfortunately I'm experiencing some pretty bad pixelation during playback of higher res. output mp4 files...
seems ffmpeg is also available for windows...your mileage may vary

mr_manny - I previously did a transcode of a video from apple/trailers, so this time I went to YouTube, downloaded a High Def Vid in mp4 format and ran the script - it worked fine.
Both the vids I did were 1280 x 720 which is an aspect ratio of 1.777. So on the script I added "-s wvga" to set the width and height. Runs with occasional slight choppiness, but no pixelation.
Also, I did try converting an FLV video, but couldn't get that one to end up looking very good - must need a different parameter, but I haven't had time to experiment.
