I recently bought a copy of Sony Vegas Movie Home Studio Platinum 11 to go with my Panasonic TM900, however I'm having problems burning Blu-rays via the 'Make Movie' wizard. The video playback seems to be fine, however there is no audio in any of the disks that I've burnt so far (about 4!). I've also tried playing back a disk in my PS3 and there is no audio output from that either. This leads me to the fact that something must be going wrong in the render/burn process. I've watched all of the training material and carried out the interactive tutorials to the letter. I've been careful in setting the project properties and have even used the 'Match Media Settings', function to ensure that it renders the video to the same settings as the imported .mts files from my camcorder. I have also made sure that I have the 5.1 surround sound check box selected. The weird thing is that I can render the video manually using the 'Render As' function in the File menu, and I can create a .m2ts file that has audio and video content which play back normally on the PC. I haven't tried burning this to a disk however as I don't want to wreck another (pricey) disk. Can anyone tell me if I am doing something stupidly wrong, or if I've failed to click on a check box somewhere?! Any help would be massively appreciated!
