Dolby 5.1 does not work with NERO

[hpschulte]

Hello,
first of all, I bought last weekend the VS 11+. It's great for me.
My Problem, I can't solve yet:
Camcorder: Panasonic HDC-DX1
Importing AVCHD to VS11+: NO PROBLEM, editing NO PROBLEM.
Now:
Exporting via CREATE DISK, HD-DVD with CBR 13.000, 2-pass, Dolby 5.1.

File is named ...*.evo
Playing with NERO-SHOWTIME : No problem
Playing with PowerDVD: NO SOUND (!)

Importing to NERO-VISION: NO SOUND (!)

NERO-VISION because of I can create a AVCHD-DVD and can it play back on my standalone BluRay-Player (disk will be recognized, but is played without sound).
My question: where the hell has the sound gone to and what do I have to do to create a NERO-conform-file.

Add.Info: I opened the file (created by VS) with the Tsunami and there was no audio track found. So, I think, VS does not create a dolby-audio-track. With stereo-settings will no probs accure - but, I have a native dolby-signal and I like to process it.
