I have a lot of audio tracks ready for a future project... english DTS ES 6.1, DD 5.1, DD 2.0 from DVD; DD 5.1 and PCM 2.0 (plus eventually analog 2.0) from laserdisc; italian DD 5.1 from PAL DVD; french DD 2.0 from NTSC DVD... the only missing things are german and spanish 5.1 tracks (and french 5.1) plus the most important, the HDTV big file... (^^,)
...almost ready for the challenge...
