Bad TALDSAudioPlayer->DurationTime return value

[SleepCZ]

Hi, i got a problem. When I use fuction AudioPlayer->DurationTime, with some songs - +-50% I got bad return value. Problem is, that one file (3:57min) returns correct value, but other one (both are MP3) returns wrong value... Does somebody have any idea where can be problem? Thanks so much for tips.

Code:

__int64 Time;
TALDSAudioPlayer->FileName = "FILE.MP3";
TALDSAudioPlayer->Open();
Time = TALDSAudioPlayer->DurationTime();
TALDSAudioPlayer->Close();
