Help! DVDA wants to recompress

I created a menu with DVDA3 into which I had inserted 3 copies of the same media (to create play all, play first half, and play second half options on the menu). DVDA said disk space used was 4.6GB.

I ended up tweaking the underlying video, so I re-rendered and used a slightly lower bitrate. Since the menu layout didn't change, I opened the DVDA project with all media offline, deleted the media from the project, put the media back online, and inserted new instances of the media into the project.

The old media and the new media were rendered in Vegas 6 using the DVDA template to mpeg (I changed the variable bitrate), and audio was rendered in Vegas to ac-3.

Now DVDA says the disk space used is 3.5GB, and tells me it is going to recompress all the video and all the audio. If I go into the media properties pane and remove the audio, the disc space used jumps to 6.7 GB.

I went into the Project Overview pane and deleted all the media, so now I have a menu shell with broken links. Disc Space used is 1 MB, which makes sense.

If I insert the media (mpg file) or drag it from the explorer onto the main menu, the Disk size used jumps to 3.5, and if I go to Make DVD, DVDA says its going to recompress.

BUT, if I open a new project, and drag the media to onto the central pane, Disc Space shows 4.6GB used (which makes sense), and if I go to Make DVD, DVDA says it will make the project without recompressing

So what the #%@%@ is going on?

Is there any way to force DVDA not to recompress the assets? I have demonstrated that the a/v is compliant and does not need to be recompressed.

Alternatively, is there any way to start a new project, import the video and copy over the menu structure and inter-button links, etc.?


I have hours invested in this menu, and I can't afford to start again from scratch.

OK, go figure, I reopened a version of the menu I had saved after I deleted the first media, and when I dragged the media file onto the main menu window, Disc Space showed 4.6GB. So I copied a couple more instances of the media, dragged the icons in the project overview pane up to the root, assigned links to the buttons, and now the project is preparing fine, not a single message.

I'd still be interested in hearing if anyone knows what happened.

My guess is that with all the switching somehow it got confused.

One thing I do that seems to work, is when re-rendering video, I change the name of the old file, use the name that DVDA knows about for the new one, then open the DVDA & the project.

Don't go by the projected file size in DVDA. Normally I just select the audio/video files in windows explorer, knowing I've got 4.35 gig to play with. I actually like to go a little bit oversized, then use Shrink to bring it barely below the max limit. That way I'm not killing myself fussing over minor size differences, or giving up quality by rendering at a lower bit rate than necessary.
