VSO Blu-ray to MKV Converter offers users the ability to convert entire Blu-ray movies, or just segments from the disc, to MKV format.
Users can choose the video and audio format to use within the MKV files (MPEG-4, H.264, AC3, AAC, DTS), as well as choosing to down-convert to standard definition or retain the high definition (720p or 1080p).
Also supports NVIDIA's CUDA technology for assisted processing.
If you plan on converting Blu-ray to a lot of different formats and devices, you may want to consider VSO Blu-ray Ultimate Converter, which includes all the features of Blu-ray to AVI Converter, but also all the other Blu-ray converters available at VSO (Blu-ray to PS3, to DVD, to MKV, to AVI, and to Xbox 360).
