I've always used 'driveropts=burnfree' to burn DVDs with cdrecord. However, according to this post
, buffer underrun protection does not apply to DVDs. But this contradicts wikipedia's article "Buffer underrun":
Therefore, a technique called buffer underrun protection was implemented by various individual CD/DVD writer vendors, under various trademarks, such as Plextor BurnProof, Nero UltraBuffer, Yamaha SafeBurn, JustLink, and Seamless Link.
Have DVD writers buffer underrun protection or not?
