Audio Missing from rendered file

I have upgraded from Screenblast to Movie Studio 4 and have encountered a problem when rendering the final project.
If I render using 'save to hard disk' and selecting Main Concept codec, the completed file can be imported to DVD Architect and a DVD burned. The first time I did this, DVD Architect informed me that in order to avoid 'recompression' I should select the appropriate option when rendering within Movie Studio i.e. use 'Burn to DVD' and send directly into DVD Architect.

I tried this with the same project (around three minutes of DV plus a ripped CD music track). This resulted in two files (mpeg video and WAV audio) which DVD Archiect imported successfully. However upon burning the DVD in this way, the audio from the project was missing.

I went back to check the source files and discovered that the WAV file was 39 MB (44.1, 16 bit etc) but was silent when played with any audio app I cared to try.

Subsequently I played around with the project and moved the audio to a different audio track. Upon rendering the file, the audio file produced was the same 39 MB, but when played back, contained 6 seconds of audio, then silence.

I can see that there is a workaround by rendering to a complete MPEG file (audio + video) but it would be nice if the 'burn to dvd' option worked as well.

Is there any noticeable loss in video / audio quality when using a combined MPEG file within DVD Architect in place of seperate streams?

At least not in my opinion. I usually create my DVD's this way, and it sounds pretty good to me. I'm no audiophile and I don't have the world's best home theater, but it sounds good to me.

Sony Tech Support kindly pointed out that this is a known problem and will be addressed in a future update.

For a workaround that works perfectly satisfactorily look at the following knowledgebase article.

I stumbled on the first sentence. Is there now an upgrade to 4.0 for Screenblast MovieStudio? The last I saw it was only up to 3b.

Yep! Not very exciting from the NLE point of view, but MyDVD's been dumped in favour of a Sony product. I'm still sticking with DVD-Lab though.

I've made a bunch of great dvd's with no problems, but I have now witnessed this first hand. And it sucks. Although, I did learn that you can render the audio file seperately from the video by simply clearing out the file name for the video portion when rendering via the "burn to dvd" option. That saved me a couple of hours. Phew.
