FCPX, Compressor and Dolby Digital 5.1

Hi all,

I had Final Cut Pro 7 HD and gone over to FCPX.

The Apple Store in Sydney told me to burn a disc with 5.1 surround sound I should export to Compressor. Tried but no sound. is it possible to burn to disc with 5.1 from FCPX?

I've been using FCP for around 10 years but FCPX is a bit of a learning curve. Even with FCP 7 never needed to use compressor as the movies I make are mainly for friends and family but now I have to have a 5.1 Dolby Digital soundtrack. I understand DVD Studio Pro did that but it's very complicated so please, even though well versed in the old FCP, treat me as a newbie on the new version.

Basically I have footage captured with my new Sony HDR- CX190 and have imported into FCPX. I have some audio I want to dub over the top which is in 5.1 AC3 but the first export only one clip came out, not everything in the timeline and no audio so sent to Compressior and it asked for settings so added them and Compressor said the sound was 5.1 surround and I processed and it burned to DVD but no sound!

You're all probably laughing as it's probably so simple I'm overlooking something that's most likely staring me in the face:

What I need to know is once I have all of my video clips, transitions and 5.1 sound in FCPX - how the **** do I get that onto a DVD or Blu Ray disc that will play all of the footage and in 5.1 Dolby Digital?

Any help will keep me from pulling my hair out!

Thanks

Dan
