The recent version of Winamp decodes HE-AAC streams from DAB+ radio system with the wrong duration.
The reason for that behaviour might be that DAB+ uses 960 sample windows, while Winamp uses 1024.
As a result, the play time of the decoded files are 6,6 percent to long.
Please check the streams yourself:

Can you please fix this bug with your next version?
