Audio incompatibility

I bought Vegas Movie Studio 6 and DVD Architect Studio 3 as a package, yet the audio is incompatible. Vegas Studio 3 outputs an MPEG-2 file with MPEG audio but doesn't give any choice about how the audio is encoded. DVD Achitect Studio 3 always re-encodes the audio to WAV, blowing out the size of the resulting DVD so it sometimes doesn't fit.
Any workarounds (apart from shelling out hundreds of dollars for the non-Studio versions)?
I would have thought that a package that's sold together should work together.

Vegas Movie Studio and Architect studio are compatible. Perhaps you may need to recheck your default settings in your VMS project settings. You have several options when rendering a movie in VMS 6 before you send it over to DVDA 3. What most folks do is render as an avi in VMS, then choose the "size to fit" option in DVDA. This method provides the most options for the software to compress your project to fit.

Another option to consider is upgrading to VMS 7 which supports
AC3 compression which will give you a lot more room for your projects. The upgrade is pretty reasonable.

I believe the default audio setting is pcm, not wave (which makes me suspect your projects setting may need checking)

good luck with it

The PAL DVD standard allows MP2 audio, but the NTSC DVD standard doesn't - you need PCM or a supported compressed format like AC3 or DTS. The NTSC DVD template produces MP2 audio, so it has to be converted. This isn't a problem with the template - MPEG2 encoders produce MP2 audio!

DVD authoring apps like to work with separate audio and video (elementary streams) - if you've encoded using the NTSC DVD template the resulting MPEG will be demultiplexed into elementary streams before the audio conversion happens. You can't get away with using MP2, but you can use a different template (I can't remember the name) to just encode the video as an elementary stream and then go back and produce the audio separately in PCM, or AC3 if you've got VMS 7.

WAV isn't an audio format, it's a file format. The audio in a WAV file is usualy PCM, so the terms tend to be used as if they're the same thing - VMS doesn't mention PCM, it only refers to WAV.

Thanks for your advice. I've upgraded to VMS7 and DVDA studio 4, so now I'm working in AC3.
Everything's going well until the final creation of the DVD. Everything in the DVD was created in VMS7 or DVDAS 4, but during the Prepare stage, I get this message:
"Warning: An error occurred while writing a file.
The file is most likely corrupted or of an unknown format. A necessary RIFF header is missing."

Any ideas? I really need to get this project finished. After hours of work, it's mighty frustrating.
