What can I say I tested all three versions, for 1.07 even two different builds and the results are all the same.
I get very rare (!) crackling sounds at low sound levels that somehow sound like those from good old records time. I checked the AC3-source: it`s fine. I tried the transcoding via wave-file (azid->wav->mp2), fine. However, and that is really worth mentioning the one-step-transcoding with besweet (ac3->mp2) is the culprit.
The point is that even for two different language streams the crackling sound appears at exactly the same timestamp.
Please check your mp2-soundfiles carefully. I don`t think that it is my hardware or software (DVD2SVCD versions tested as given in the subject).
Okay, here is the work around. Start DVD2SVCD, wait until besweet starts, open the dos window, press ctrl+c. This aborts processing audio stream 1. Do the same for audio stream 2 (if set for processing). Now let the encoder start up. When it actually commences counting the time and frames, push abort.
Now you have the time, and the processor capacity to process your audio (BTW, in that way you can create mono streams, one stereo, one joint stereo channel and so on). The besweet GUI is fine for that task, just make sure two process via wave.
When finished copy the (two) audio stream(s) back into your movie-folder, renamed correctly (Encoded_audio_1.mp2 - hope that`s correct, writing all this from memory). After that restart the encoder by hitting "Encode" and let DVD2SVCD finish its work.
If someone would like to confirm my findings, take the A.I. PAL DVD, check the English and German soundtrack, go into the mp2-file at 22min and wait for the scene after the imprint of little Dave. Some low volume music is heard when the bathroom scene starts. This is where you can hear the crackling noise.

PS. I have just the idea that a bit-by-bit comparison should easily produce the differences of the mp2 output files for the two methods. Has this been done already?
