Special features:

With TV Rips with AC3 6ch audio it happens that the first frames have only 2 ch. In the encode audiostream section there is a button for this. If it is selected, the target file will be patched to full 6 ch. This button is only available if the source file is or contains an AC3 6ch file.

Another great thing is that you can convert the soundtrack of a 25 FPS PAL movie to an e.g. 23.976 FPS NTSC soundtrack or vice versa and, if desired, also adjust the audio pitch.
