yes we used some software called stienberg (great stuff if you can get a copy for free ) the damn linces cost over 1500.00 us dollars for it ahhhhhhhhh

but take the 2.0 track slide it in your cpu play with it and you will notice IT IS THE PCM AUDIO TRACK AND IT IS UNCOMPRESSED AND RAW BIT FOR BIT the 5.1 was done for market demand perpose

also let me send credit out to TR47 that was his controbution to the factory punch set he asked and he shall recieve
the pcm track was his idea

there is 2 audio tracks on the set

2.0(pcm)
5.1 remaster from stienberg
