warning from dvd Maestro: reason...?

[Bruxo]

Hi, you guys. That's the first time i'm receiving this warning from dvd Maestro(in 3 years of using).

1 Warning :

- During Muxing at least one instance of Buffer under-flow was detected. This is due to exceeding the Max. Bitrate.

The weird thing is... i'm using ripped material from dvd's already authored by me(using dvd Maestro) 2 years ago... i'm doing the same stuff as always(i'm improving the quality of the subtitles, i'm using a better translation version, so, i'm authoring all over again the same material)... using the same files from 2 years ago... but now, almost all that material present those warnings on Maestro. I've checked the dvd's, burned a couple, and they are fine. But what is bothering me, is that i don't know why this message is coming. Any tips?
Thank you so much!

did you cut the mpegs? or how did you demux them ?

sometimes demuxing in DVD Decrypter would cause this error to show up -- using moonlight xmuxer or tmpgenc or cmd line bbtools would not ..

Oh, yeah, i forgot to say, i've used decrypter to rip the files(using the "demux") from the dvd. Eeheh, i always use DD. Sometimes, only sometimes, i use dvd Shrink to rip something. Thanks a lot, i'll try use those sofs you said, using the same files, to see if Maestro will give those warnings again. Thanks a lot!
