Can't encode MPEG-2 at more than ~3Mb/s

Summary of the bug: I'm trying to convert a 720p25 video to DVD-spec 6500kbps MPEG2, but the output is <3Mb/s instead. The subjective quality is not that good, there are blocks in the background and the picture lacks sharpness. I'm using ffmpeg version git-2012-09-26-299c0b3.
The source video is a remuxed Sherlock.S01E01.720p.BluRay.x264-AVCHD, that can be easily found in P2P sites. With some guidance I can try encoding the original BluRay, but ripping it on linux has proven itself way too difficult for me and I figured it would be the same.
I originally used a much more complicated command line, but the issue is still there with the stripped-down
ffmpeg -i "$1" -target pal-dvd -b:v 6450k -an -pass 1/2 "$1".mpg -report
I've attached ffmpeg's reports and the two-pass log, please tell me if you need anything else, I'll try to reply as soon as I can. Thanks!
