New released Pavtube ByteCopy lets you rip commercial Blu-ray Discs and DVDs into MKV files with all contents retained without quality loss. A most important feature is to encode video files with more than one audio stream. You can select two ore more audio streams to the output file or encoded the selected audio streams into desired codec (AC-3, DTS, PCM with 6 channels, MP3, MP2 stereo). The software captures audio streams by language. You can set desired language for once and all, as it is able to remember your preference and select the audios of preferred languages when a new Blu-ray Disc is loaded. Pavtube Studio guarantees that the software will always keep pace with the latest BD copy-protections to read all commercial Blu-ray Discs on market. The following guide tells you how to keep English and French audio tracks all the time with Pavtube ByteCopy software.
