No.

DVDShrink only accepts VIDEO_TS folder structures as input. If you can ever even figure how to get mpeg1 into one of those, it probably still wont work ;)

Setting the min bitrate to 0.57 * average-bitrate...

Setting the min bitrate to 0.57 * average-bitrate will likely increase it above the old standard 300kbps, right? So will that not reduce video quality since more bits are used to encode frames that...

I've always thought that any spatial filtering softens divx sources too much as they're already pretty soft compared to DVDs so I tend to leave it out and take the CQ hit - I just prefer the results...
