DTS 5.1 (1.5 Mbps) to AC3 5.1 (640 Kbit) How?

[pasta03]

Hay!
I would like to ask if anyone knows a way to transcode DTS 5.1 (1.5 Mbps) to AC3 5.1 (640 Kbit)? Everything I've tried has failed...
I have tried VLC, Belight (0.22, 0.21), dts2wav...
Any help would be appreciated!
:thanks:

1) Without intermediate wav files:

1.1) Foobar2000. Use foo_input_dts.dll like decoder and Aften encoder.

1.2) AviSynth methods (Bepipe, BeHappy or SoundOut). Use NicAudio.dll like decoder an Aften encoder.

2) With intermediate wav files. Use Tranzcode like decoder and Aften (AftenGUI) like encoder.
