Audio prblem with MPEG and Video Studio 9

Hi. I'm having some problems with audio and hopefully it's just something simple I'm missing. I'm running Video Studio 9 (an SE edition, not a trial) and I'm trying to make a DVD from MPEG files captured from my Sony Handycam. When I open the MPEG file from Windows Explorer, the movie plays fine with audio but when I open it in VS9 and try to play it, there is no audio.

Here are the file properties...

File Format : NTSC DVD
File Size : 47,616 KB
Duration : 49.049 seconds

Video Type : MPEG-2 Video, Upper Field First
Audio Type : Dolby Digital Audio

Any idea why this won't play in VS9 but it will in Media Player? VS9 will play other mpegs I have but they aren't Dolby. You think it may be a Dolby Issue?

Yes. The SE versions come free with hardware, and do not contain a capacity to handle Dolby. Only the full versions (i.e. non SE) can handle Dolby. Dolby requires a licence fee for use of its software, so it is not included in free copies of the main program.

That's why.. The SE version is a free version. Dolby does not allow the use of its product in free versions. They require a license ( translates into $$$) to use any of their technology. So any product that is released as a Free, trial, or like yours an SE (Simple Edition) then the dolby is not included.

Well then, that's just stellar. Any way I can use a third party software to convert the audio on my MPEG file from Dobly to something VS9 can actually work with?

If you go to www.videohelp.com and do a search there for something labelled 'AC-3 filter', you can download a filter which will at least allow to sucessfully download your Dolby so that VS can 'see' ('hear'?) it. But of course you will need to convert it then to mpeg or LPCM audio as output for your project. Sorry I don't have the exact address of the AC-3 filter, but I am at a beach house for the weekend, and I don't have all my files on my computer down here!
