@Cleven-Brown I agree. Media is dead; long live media! The current version is indeed worthless; it's 32 bit and inconsistent in operation (at least for me). Also, the notion that SoundForge is an "acceptable" replacement due to higher demand is, unfortunately, not a good choice: I already own SoundForge and thus gain nothing new. I would guess that a number of Vegas Magix customers also have it; I could be wrong and it's a great offering. Unfortunately, it also appears that, beneath the surface, SOMEbody is upping the ante on licensing charges.
Reality check! Commercial DVD/BD sales are going down - DVD/BD retail prices are getting ever lower. Streaming is going up very quickly and has been doing so for quite some time. Products like CyberLink's DVD provide an alternative to physical media as do so many forms of media renders like mp4 and players. Even Sony pulled out of their ultra expensive DVD creation software long ago (can't remember the name). From a recent look into this, there seems to be only one DVD/BD creation software company left catering to the professional sector - and its very expensive. Most of the rest seem to be aimed at the low cost domestic market - do a Google/Bing search re this.
Yes, I think that DVDA is great and I still use it for BD, but technology and popular usage of media has left it behind principally because physical media is no longer as popular as it used to be. Some 20 years ago, DVD made VHS and Beta obsolete, now DVD and BD is progressively being made obsolete by other technology.
@ Dexcon I assume you are referring to yes, the astronomically expensive Scenarist. There is, however, at least one companies offering a -uh, comparatively lower but still pricey, professional offering - DVDLogic (more buying options than you might guess; also offer UHD authoring capability; ranging from "costly" to "astronomically expensive"). Also of note it that Blu-Ray have extended format specs coming up with 4K Ultra HD (requiring requisite hardware to play and view of course). Whether this will be adopted widely enough remains to be seen; stats as of 2 years ago were encouraging with Hollywood releases of major stuff, e.g. Guardians. All of this is to say that Magix is wise bailing from this market segment. Having failed to keep up, the barrier to entry is prohibitive. The disc world may converge a la Spielberg's theatre world: the few, the most excellent, the expensive - a limited market for today's quick and dirty generation all of this aided and abetted by a certain virus! (or maybe the vinyl route?) or....
