BeSweet Commandline Surround

[Oline 61]

I am trying to transcode a 5.1 AC3 from a DVD to a 5.1 AAC with BeSweet using the Nero dll. I am somewhat confused aobut the avid commandline settings. I want to maintain the surround sound from the AC3. Right now I am planning to use this commandline:
-azid( -s surround -c normal -L 0db --maximize )
Will this achieve what I want? What other setting could I use?

EDIT: I just came up with a few more questions.

1. I am using the latest ffdshow (Celtic Druid) audio decoder, and my output is 640kbps AC3 over SPDIF to my Dolby Digital Reciever. The reciever says it is recieving Dolby Digital surroung. Are the channels still seperated as they are in the 5.1ch AAC input?

2. Also, if I choose HE-AAC and Export ISO AAC stream from the BeSweet commandline, is the resulting .aac SBR HE-AAC or just regular LC-AAC?

3. Also, using the exact same command-line, with lc-aac my file is about 3x as big as an identical commandline with he-aac. WTF?

Must be:
-azid( -c normal --maximize )

With your settings you get a stereo Dolby surround ProLogic:
-s surround : azid make a downmix DPL from 5 channels FL-FR-C-SL-SR to 2 channels.
-L 0db : the LFE channel is mixed with FL and FR without attenuation, then sounds twice volume (in two channels) than original.

You need also for a correct channel mapping:
-dimzon( -dllname bse_Nero7WA.dll -6chnew ...)

Use last release of Belight.

More questions:
1) Yes, if ffsdhow is well configured and your input is a aac 5.1 (with your BeSweet command line is aac 2.0)

2) HE-AAC is always SBR HE-AAC. With Export ISO AAC stream option you get a .aac file instead a .mp4, different container but the same audio stream.

3) LC-AAC is for more quality encoding and more bitrate than HE-AAC, then the file is bigger.

When I use -dimzon( -dllname bse_Nero7WA.dll -6chnew ...) Besweet quits without doing anything. The log file indicates an error connecting to bsn.dll. Can I use this instead?
BeSweet.exe -core( -input "" -output "" -logfile "" ) -azid( -c normal --maximize ) -bsn( -6chnew -cbr 320 -codecquality_high -aacprofile_lc ) -ota( -d -25 )
This creates a valid 5.1 channel .mp4. Is there something wrong with the channel mapping in this mode.

BTW, I have nero 6 and are therefore using it's dll's. I don't have access to Nero 7.

To make things more confusing, when I use HE-AAC I get this:

(I'm talking about the table with sample rate and start/stop).
I don't get this using LC-AAC. This isn't anything bad is it? Does it have something to do with SBR?

Here is a comparison shot (top is HE, bottom is LC):
