Bitterbpp project can make DVD backups to matroska under Linux.
Bitterbpp may not be used to make illegal copies of DVD movies; in fact, it functionally cannot since it depends entirely on MPlayer and lsdvd to read and process the DVD structure. So if you cannot legally (local laws, etc) make a backup copy of a DVD you legally own, you may not use this software in conjunction with MPlayer to do so. In fact, if for you the previous statement is true, I wouldn't even visit the MPlayer site, let alone download MPlayer.
Bitterbpp is designed as a lightweight, feature rich GUI "wrapper" to MPlayer, lsdvd and various other related software. As such, bitterbpp is an application written in Perl, utilizing the Gtk+ 2.x Perl bindings. Since it has some typically non-portable methods and system calls designed for Linux compatible systems, I don't suggest using this in any untested environment (Mac OS X, Windows, etc).
Here are some key features of "Bitterbpp":
· Recompresses any selected movie track in 2 passes (or n passes if desired) using one of four configurable codecs, to fit chosen space and scaling requirements. Scaling calculations are based on bits per pixel estimates, hence the name bitterbpp :)
· Unlimited audio tracks (in original AC3 or DTS, or recompressed to Ogg Vorbis) and unlimited subtitle tracks, with proper language support.
What's New in This Release:
· itterbpp-refresh separated from bitterbpp.
· Revised program structure.
· Updated documentation.
