min quality has nothing to do with min bitrate. Min quality deals with the quality of the frame. So if the PSNR is off, min quality causes the frame to be reencoded at a better quality. Min Bitrate just prevents the bitrate from dropping below a certain level. They both affect quality, they do not work together.

One thing Min qual does do is bloat your final AVI filesize. It also slows encoding.
Of course that's only a prob if you like to work to a set filesize, say 1 or 2 CDs. Many experienced users report they set Min Qual to 0. Most movies look OK on this setting. Min Qual was not a feature of the earlier NanDub versions. JB |

Agreed. Min Quality is not Necessary if you are making a 1 or 2 CD rip. Why? Because if you set your resolution right and set Nandub right, then you should not have a problem with quality and all min. quality will do is bloat your file. If you are a quality freak and don't care about size, then it can be useful, but not necessarily as PSNR is not a great measure of quality. However, Min Quality of 1 with an antishit of 16 seems to prevent bunches of keyframes in some cases, so I use it for that.
