I try to use Sonic Foundrys Soft Encode to make my own AC3 file, I load five different .wav files and try to encode to a .ac3 file but if i make a file longer than 15 seconds soft encode crashes, and if I make a file shorter than 15 seconds the sound sometimes get distorted.

I can listen to .ac3 files on my system and I use win XP.

Any help would be appreciated!
