Simply rip a section from one of your DVDs and re-encode it. Motion scenes and lower values of -q seem to tickle the bug (but the problem can appear almost any time).

Actually I'd hope you would resurrect and do battle with, and hopefully drive a stake thru the hear of, the "-q" option. Make that thing go away! Please! Specify a rate, a minimum and a maximum. THe encoder should automatically, I think, adapt the quantization (-q) with NO help from the user except for the desired average bitrate and perhaps an absolute "do not exceed" value. > Here's a deal.

Sounds all great to me, especially the last point ;-) > Here's a deal.

I'll have some testing material next week; and unless your recent commit already solved all problems, you may be sure that I continue nagging you.
