Burning CSS to recordable DVD requires special DVD burners and special-made recordable DVD-R media. A first Qflix drive from Pioneer including special Qflix media became available end of 2008. Prices of drives and media are higher than standard DVD drives and media. Dual-layer Qflix discs (DVD-9s) are expected to be available in the second half of 2009.

Recordable CSS DVD media are not writable in standard DVD burners and will not be recognized as blank media. Using Qflix technology with DVD-RW, DVD+R, and DVD+RW is technically possible but has not been pursued by the companies involved.

It is possible to use standard DVD recordable media to record CSS with more advanced disc writer technology, such as the DTR PDR. This removes the redundant requirement for the use of expensive custom media and all of the related infrastructure costs.

Usage

Qflix drives, media, or software are available from or used by Allied Vaughn, Amazon CreateSpace, Blockbuster, CMC, CinemaNow, Dell, Pioneer, PLDS, Plextor, Primera, Rimage, Ritek, and Verbatim/MKM.

A working alternative to the Qflix system is offered by Australian company DTR Limited. It relies on a special DVD recorder named the PDR (Protected Disc Recorder) that is capable of writing not only CSS content to standard DVD recordable media, but it is also able to perfectly replicate almost all optical disc copy protection systems. As it doesn't require any kind of special media, there are no additional costs or requirements for new media types. Furthermore, the higher burning speed and reliability (including playback compatibility) of the discs producted by the DTR system have been proven to be in advance of that provided by the Qflix system.
