I changed over from Win XP to Win 7 a couple of weeks ago. For starters, DVD WS2 did not work. I researched this on Google and found the solution.
Everything now works including sound. What is the solution?
Windows 7 does not come with DirectX, the best version being DirectX 9.0c. I believe DirectX comes on the DVD WS2 install disk. Another file that does not come with Win 7 is d3drm.dll and this can be found by a Google search. A couple of sites have this file available as either a RAR or Zip file. This needs installing into the DVDWS2 program folder.
I suspect that DirectX takes care of the sound problem experienced by other users in this forum.
When you re-install DVDWS you need to right click the DVDWS shortcut and click properties. Go to the compatibility tab and set compatibility mode to Windows XP SP3. Uncheck "Disable Desktop Composition" (aka Aero) to prevent preview crashing the program.
I am running the 32bit version of Win 7 Ultimate but believe that it will run under 64 bit as well. (this info may apply to Vista as well)
Pity that Corel decided to ditch DVDWS - in my opinion the best DVD authoring program ever produced! Can't see that with some additional programming that DVDWS could be made to handle HD video. There's just nothing around that matches DVDWS for features and ease of use.......
