Dolby Digital vs. PCM
I am working on a children’s DVD with source audio that’s in 2 channels. I have plenty of room to spare on the disc, and am wondering whether to encode with PCM or Dolby Digital.
My considerations are:
1) Does one provide better sound quality than the other?
2) IS one more broadly compatible than the other?Thanks,

Only those people with Golden Ear using a top dollar system in a pristine listening environment will probably think that PCM sounds better than Dolby. But your normal listener won’t hear a difference and might even think the Dolby sounds better.

No.Dolby, as you probably know, will uses much less bandwidth. So, you can throw the extra bits at the video encode. I have seen many cases where DVD-R burns, using PCM and a high bitrate video encode, won’t play as well as the same video encode but with Dolby audio. Your milage may vary.
