Did you change the level to 3.0 from 1.3 like I suggested?

Here's the line I use for iPod videos. I get videos that, when played back and upscaled to HD on my PS3, look as good as the DVD source (and yes, they play back perfectly on iPods too):
--profile baseline --level 3 --preset fast --pass 2 --bitrate ???? --stats ".stats" --thread-input --deblock 0:0 --no-cabac --b-bias 0 --scenecut 40 --ref 1 --qpmin 16 --vbv-bufsize 2000 --vbv-maxrate 2500 --rc-lookahead 50 --aq-mode 1 --aq-strength 1.0 --merange 12 --me umh --subme 6 --partitions p8x8,b8x8,i4x4,p4x4 --no-8x8dct --trellis 0 --psy-rd 1.0:0 --no-mixed-refs --no-fast-pskip --output "output" "input"

It's essentially the iPod5.5g profile, but with some tweaks I added. The bitrate is source dependent, with reasonable values being anywhere from 800-1200 depending on the complexity of the source material. Movies with a lot of static shots, or night-time sequences require less; heavy noise, grain, and or movement require more. I just completed a 688x386 iPod video of "The Shining", which compressed perfectly at only 900 kbps.
