 - 11th February 2007 version 0.3.2 covers sequential DVD-RW and DVD-R with
  multi-session and with DAO.
-
- 12th March 2007 version 0.3.4 supports DVD+R and thus covers all single layer
-  DVD media. Code for double layer DVD+/-R is implemented but awaits a tester
-  yet.
+  This means all single layer DVD media except DVD+R are supported now.

-About blank, appendable and finalized DVD+R :
-
-In the beginning a DVD+R holds an empty session and the Incomplete Fragment.
-From these one may spawn reserved fragments or one may write directly to
-the incomplete fragment. As soon as this is done the empty session becomes the
-open session which finally needs to get closed. By closing fragments and
-session a new empty session with empty Incomplete Fragment gets spawned.
-So the disc stays appendable.
-
-A DVD+R may hold 153 closed sessions with a single track each.
-The open session may hold up to 15 open fragments. But on closure of the
-session those fragments together form a single logical track.  So one will
-usually only use a single fragment for sequential writing. 
-(mmc5r03c.pdf 4.3.6.2)
-
-The disc may get finalized by another close command so that no more data can
-be written.
-(mmc5r03c.pdf 6.3.3.4.4) 
-
-
-------------------------------------------------------------------------------
-Writing a Pseudo Session to DVD+R :
-
-Session writing has to be pseudo because only one logical track per session
-can be distinguished. So actually there have to be written multiple sessions
-to mark multiple tracks. The pseudo session cannot get marked on disc and thus
-the tracks of a pseudo session cannot be grouped accordingly in a TOC.
-
-Speed can be influenced by B6h SET STREAMING , speed capabilities can be
-inquired by ACh GET PERFORMANCE. It is advised to set only speeds and sizes
-which are returned by ACh.
-(mmc5r03c.pdf 6.39 SET STREAMING, 6.8 GET PERFORMANCE)	
-
-No mode page 05h is to be sent.
-growisofs sends a page but the specs clearly state that one shall not do.
-(mmc5r03c.pdf 7.5.3)

-It is optional wether a track size is reserved in advance or not. Eventually
-this is done by 53h RESERVE TRACK, RMZ=ARSV=0. Reservation size should better
-already be aligned to 32 KiB.
-(mmc5r03c.pdf 6.31)
-The specs promise to pad up the track if not enough data get written.
-(mmc5r03c.pdf 6.3.3.4.2)
-
-Next Writeable Address is fetched from the reply of 52h READ TRACK INFORMATION
-with track number FFh.
-(mmc5r03c.pdf 6.27)
-Since the fixely set write type is 16-block packet, full 32 kB buffers have
-to be transmitted via 2Ah WRITE.

-
-When writing is done, it is mandatory to force the drive's buffer to media by
-35h SYNCHRONIZE CACHE.
