BDtoAVCHD is a tool to create AVCHD discs from Blu-Ray or HD MKV files. As output we get the folder structure ready to burn to a DVD5 or DVD9. The AVCHD format allows playback the same type of content that a Blu-Ray and holding high definition (1080p) but on DVD5 or DVD9 media. It is ideal for backing up Blu-Ray with much smaller size and maintaining high quality. The recorded discs obtained are compatible with almost any Blu-Ray player and PS3. Also can convert Blu-Ray to MKV and Blu-Ray 3D to MKV 3D SBS (side-by-side).
