ConvertXtoDVD 2 many b frames?



What does to many b frames mean?

i’m trying to burn a converted to dvd avi but one file is 2.83 gigs long (only one sectio.
So i decided 2run it back thru to create chapters cause it refused to even start burning, when trying 2 urn from nero it evensays file size over 2gig you need 2 use a diff method (something similar). when i finished the first try i noticed the chapters were thre butthe figures were now elongated so i went to prefs and switched back to auto instead of 3:4 ratio… now another hr wait while it converts that one ig a… chapter again.
i’m glad i purchased this software, just a bit of a learning curve but im getting there…

thanks VSO
