Great. Thanks a lot. It seems now rc is being quite efficient, and
infinite loop is fixed.

However, I will again bother you. I got another sample which seems to
cause weird high q on I frames.

qprd_high_i.mpg on mplayerhq.

latest svn.

ffmpeg -i qprd_high_i.mpg -flags +qprd -b 3995k -minrate 3995k -maxrate
3995k -bufsize 2500k -mbd rd -bf 2 -mblmin 1 -lmin 1 test.vob

First I frames are really visually blocking. If I remove -lmin -mblin,
frames are correctly encoded.

See q values attached, from frames 5 - 20.
