Audio not burning to DVD
I have edited and rendered a video 81 mins long in Sony Vegas Movie Studio HD Platinum 11 which I want to put on DVD
I've followed the tutorials and used the bit rate calculator which gives Min 376000, Av 6264000, Max 7832000 and I've used a 15% safety margin (I'd previously left it as 4% and 10% with same result as below)
The rendered video is 3.68 GB and audio 111 MB
In DVD Architect Studio I've set properties to 720 x 576 PAL and it says the project size is 3.87GB and bit rate is 6.922. The default bit rate is 8.000. I've tried with both changing the rate and leaving it as 8.000 and it gets to a point where it says the project is too big for the chosen media. Do I want to continue? Which I do and it burns the video and not the audio.
If it helps render time is around 3 hours and burn to DVD about 15 minutes. The PC is running Windows Vista Home Premium Intel Cre 2 Duo CPU E7300 @ 2.66GHz
I've gone onto Preview and it plays video but with no sound. Both video and audio files have same name and are in the same folder. If I click on Track Media it gives path to video file but says Audio 1 None
Do I need to increase the safety margin or is there something simple that I am doing wrong?
