Audio & Data - What's the difference

I don't get it, for a CD data disc, if 1 bit goes missing, it's a big deal, the
reliability of the reading is questioned. That's why reading data files is
usually 100% bit for bit reliable.

So what's so hard about reading audio tracks? Why is there software like
EAC? What's so hard about reading bits off an audio track?

Data discs have an extra layer of error detection and correction code that audio discs do not have.

Data discs usually use mode 1 and can fit 700MB,audio and S/VCD discs use mode 2 and can fit 780MB(80min).A drive reading a mode 2 disc is more saceptable to errors because it doesn't use error correction,that's why copy-protection is more effective on audio CD's.
If you have a CD you can't read use IsoBuster.

Does this mean if I listen to the soundtrack of a DVD, it will be of better
quality than from a CD in a player?

If you are are talking about DVD-AUDIO(96khz/24bit or PCM) then yes,if you are talking about DVD-VIDEO(DTS,AC3) then no.
