DVD Analog/PCM audio output

:confused: When using DVD2VCD, on the Conversion β€œTab”, it shows two audio tracks AC3/6 - 0x80 and AC3/2 - 0x81 (which I assume are multiplexed into the VOB files). If the DVD is played on a conventional DVD player (WITHOUT an onboard DD or DTS decoder), where is the analog output coming from?!? Or for that matter, if you set the DVD player output to PCM, you get a standard 48K PCM digital stream. Is there another unencoded PCM bitstream stored somewhere else on the DVD? What am I missing? Thanks!
