Hi...
i use a batch file for my ac3 -> ac3 transcoding. As input i'll use mpg files which are read with vobinput.dll.
BeSweet will crash if i use -azid( -g -3db ) (or any -g command). If i feed the same batch file with the demuxed ac3 file (of the mpg which crashed BeSweet) all works ok.
The noticable difference between mpg and ac3 file as input (beside the crash) is that the whole mpg file is scanned for the maximum gain and the ac3 not (approx. 9 of 120 minutes are scanned).
Regards,
Gerd
