File to mobile failure and FPS dropping

[LignGeorge]

I have a problem ,when I use file to mobile fps are dropping slowlly.I found that dvdfab fills slowlly the ram usually until it reathes 1,7GB and close without an error messege( but rarelly i get the messege ''out of memory'' if it reaches 2GB).Sometimes FPS reathes 0 and remain that way if idon't close dvdfab.Other times completes the task before close.
I have 6GB ram and windows 7 64bit so I always have free memory.

When I try to compress a file from 3.5GB to 1.5GB for example task 1 srart normally and fps rising but after 2 minutes are dropping from 185 to 120 in 4 minutes and closed.
Settings: max memory but i tested every option from low to high,turbo cpu enabled.What is the problem?

NOTE:I don't have this problem when using DVD to mobile

You can often use MediaInfo to get details of the source file.

I also recommend providing the DVDFab log files (instructions in the same sticky thread).
