BeSweet creates invalid AC3 in payload mode with positive delay

[RB]

Hi,

I tried to use BeSweet 1.5b16 to correct a positive delay (+40 ms) in an AC3 file extracted from DVD with DVDDecrypter. The command line I used was:

BeSweet -core( -input "E:\DVD2DVD-R\MonstersBall\Asset\VTS_01~1.AC3" -output "E:\DVD2DVD-R\MonstersBall\Asset\Encoded_audio_1.ac3" -payload -logfile "E:\DVD2DVD-R\MonstersBall\Asset\Encoded_audio_1.log" ) -ota( -d 40 )

Here is the log file

However, I cannot import the transformed AC3 into DVDMaestro, I get an "Media detection" error message. This happens only with positive delays, correcting negative delays (i.e. -ota( -d -40 )) results in a working AC3. Any ideas?

No one else is having a problem with this?

I think I found that earlier already but forgot about it again. I think DSPGuru has to comment this. Maybe it's got to do with the size of AC3 frames (like the cutting problem of AC3 audio in NanDub).
