Cannot create Blu-ray disc with proper 5.1audio

I am a newcomer in this forum, an amateur Hammond organ player and a hobby Edius 5 and Vegas Pro 8 user. I mostly make - beside the family videos - recordings of the larger concerts of my amateur classical rock band using 4 to 6 home video cameras.
I do multicam editing in HD 1920x1080 50i by Edius 5. Then I transfer the cut video using Canopus HQ AVI to Sony Vegas Pro and create - from the multitrack (24 tracks) audio recordings remixed by Cubase 5 - the Dolby Digital 5.1 and 2.0 .AC3 audio files and finally the DVD authoring is done by DVD Architect 5.0b.
All the settings I use both in Vegas and Architect are 5.1 surround settings.

My problem is that when I change the project properties before burning the disc in Architect, depending on whether I set to prepare Blue-Ray disc or PAL DVD (both are set for 5.1 surround) the same audio tracks behave differently:
In case of PAL DVD the audio tracks are not recompressed and the burnt DVD
has one proper 5.1 surround track and also one stereo track.
In the case of Blu-Ray disc both audio tracks are recompressed (DVDA message: reason for required recompresson: media is not compliant with the disc format) and on the burnt Blu-Ray disc both audio tracks are 5.1surround tracks, with silent surround speakers and the front speakers have wrong stereo image.
I tried in the morning to render out by Vegas both a 5.1.wav and a 5.1 .w64 audio files, but DVDA did not recognized them. So the final pictuer is: 5.1 AC3 files are recognized, but - just in case of Blu-ray settings - they are recompressed with a wrong result, while other 5.1 file formats are not recognized by DVDA.
Can somebody suggest me a solution?

DD Pro or DD studio?

You will have to use the Dolby Digital Pro settings in Sony Vegas pro. The 5.1 files made with Dolby Digital Studio are not Blu-ray compliant.

I believe arthur is on the right track and it sounds like you're using the STUDIO encoder which is an uncertified encoder. It will re-compress badly every time with Blu Ray. You must use the PRO encoder that comes with DVDa PRO

I don't think that can be the case as DVDA Studio doesn't support Blu-ray.

Mike,

Vegas Pro includes with 2 Dolby encoders. One is called PRO and one is called Studio.

And to save you the disappointment of discovering that the default Dolby Digital Pro 5.1 templates do not give you the same levels as your mix, here are the correct settings:
"I've run some exhaustive tests with calibration test tones and done extensive reading of the Dolby metadata specs, and in reference to your question about the most accurate reproduction with the AC-3 Pro Encoder, I am prepared to make the following recommendations with notes:
Good luck from a retired B-3 player.

Thanks to all of you!
I did use the "studio" encoder and it was perfect for the conventional DVD.

I have just made a short trial by the "AC3 Pro" encoder and now I have both a correct 5.1 track as well as a stereo track on the disc, so my problem is solved.

Thank you also for the advice related to the proper settings of the "AC3 Pro" encoder!
