I'm creating a DVD and was wondering what to choose project settings -> change MPEG settings -> customize -> compression -> audio settings --- LPCM audio or MPEG audio or Dolby Digital audio?
What does these different options do to the sound and the size of the final file?
Audio settings?
Summary...
Normally just choose Dolby with the highest bitrate for the compression. This provides good quality audio, and allows higher video bit rates and longer total length than uncompressed PCM.
Every DVD player can play Dolby audio.
PCM is uncompressed at about 1.5Mbit just for the audio and requires the most space. But this will preserve the original 48KHz/16bit/stereo audio of a DV recording without changes. Every DVD player can play PCM.
MPEG is compressed and the quality depends on the chosen bit rate. Actually only the PAL DVD spec (not NTSC) allows this audio type, but newer NTSC players will play it anyway AFAIK.

LPCM is pure uncompressed PCM audio. It is similar to CD audio, except the sample rate is 48kHz instead of 44.1kHz. It takes-up lots of space, over 1GB for 90 minutes.
Dolby is compressed. it takes-up about 1/5th the space of LPCM (depending on the bitrate). This leaves more room for the video, allowing you to use a higher video bitrate for better video quality. Dolby is the only (compliant) way to put 5.1 channel digital sound on a DVD.
MPEG is compressed. The compression is similar to Dolby. MPEG is not compliant for NTSC DVDs (North America). So some NTSC players won't play it. It is compliant for PAL DVDs.
