DVD Authoring software suggestions

[andris]

I have just upgraded to Win7 64 and now find that the DVD authoring program I use isn't happy. Consequently I am looking for suggestions for a suitable replacement.

The DVD menu structure I am after is extremely simple :

a/. One Main menu listing multiple titles
b/. Titles are chaptered
c/. No sub-menus listing chapters.

I was able to make this simplest of menus with Ulead's "DVD Workshop 2" which now needs replacing.

Tried "DVD MovieFactory 7" and the authoring function within Edius 5.12 and found both programs automatically create sub-menus for the chapters and there seems no way to stop this happening.

I really liked DVD Workshop and it's key features important to me were :

a/. easily create menu components & navigation structures
b/. no re-encoding of mpeg compliant files ["SmartRender"], making for very fast DVD image creation.
c/. Title audio level is adjustable ( attenuate / amplify ) and
d/. if a Title's audio is adjusted, only the audio track is re-encoded, making for rapid re-encoding of the mpeg file.

Considering the above, can anyone recommend a DVD authoring program that is Win7 64 compatible and has the above features?
