Errors using Bsweet to convert AC3 to WAV

[Harddrive]

I'm working to convert the 2ch soundtrack of a concert DVD to a WAV that I can burn to CD and play in my car. I have used DVD Decrypter to get an AC3 file by demuxing the 2ch stream. I am then using Bsweet with the BeLite GUI to convert the AC3 to WAV. The first time I tried this it worked and I got a WAV that played fine, but was too long to burn on a CD. I then tried removing various chapters from the DVD Decrypter list so that I would get a smaller file. However, Bsweet always gave me the same error, #47 bad configuration for AC3enc. Thought this was an issue with removing chapters in the initial rip, so I went back and re-did from the beginning, ripping all chapters like I did the first time. Now even this AC3 will not work in Bsweet! Any ideas what might be going on and how I can fix this? Here is the log file I get when I run Bsweet:

ac3enc is for ENcoding ac3's, i believe all you want to do is decode it to a wave file. try this one:

BeSweet.exe -core( -input "C:\BSWEET\VTS_01_1 - 0x81 - Audio - AC3 - 2ch - 48kHz - DRC - DELAY -66ms.ac3" -output "C:\Documents and Settings\slades\My Documents\MISC_DOC\Stereo\BSWEET\VTS_01_1 - 0x81 - Audio - AC3 - 2ch - 48kHz - DRC - DELAY -66ms.wav" -2ch -logfile "C:\Documents and Settings\slades\My Documents\MISC_DOC\Stereo\BSWEET\VTS_01_1 - 0x81 - Audio - AC3 - 2ch - 48kHz - DRC - DELAY -66ms.log" ) -azid( -s stereo -c normal -L -3db -g 0.90 ) -ssrc( --rate 44100 )

the --rate 44100 is so it will conform to an audio cd's sampling rate. Using the BeSweetGUI, make sure you check PCM WAVE as your output and check the SSRC to get the sample rate conversion going. The -g 0.90 you can do with or without depending on the source and your personal preference. I like to always put it in there to avoid clipping in loud tracks and to up the volume in quieter tracks.

Well, I still can't get this to work using the BeLight GUI or the BeSweet GUI. All settings are as you suggested (output is WAV file, stereo mode, 44.1kHz sampling rate. Get the exact same error message in the log file.

I have not used a command line program in years, it will take some time but I will try that next. Thanks for your help on this. Seems like it should be easy and straight forward.

I was finally able to track the problem down to some errors in the input I was giving the BeSweet GUI. Chalk this up to my confusion in understanding how to tell the GUI what I wanted to do. The example command line was very helpfull - I fooled around with the GUI settings until I got the command line in the GUI to match the suggested one.

Thanks for your help!
