DVD Shrink - too many choices for audio

[j123vt_99]

ok.. i'm trying to copy a dvd using dvd-shrink

my choices for audio are
ac3 2-ch Unspecified - 197 MB
ac3 5.1-ch Unspecified - 188 MB
ac3 2-ch Unspecified - 110 MB


can i just use 5.1 or will i be missing something?

[jtoolman2000]

Yes, youo can use anyone you want or if the whole dvd you are trying to copy fits, just leave them all checked. That way everyfeature in the menu will work. If you just want the movie, and your tv is a simple mono unit, pick the first of the 2 channel ones. There is usually a second two channel one if there are commentaries. I just keep the 5in1 one and t hat works with all TVs.

what is the dif between the 2 ch ones? the dvd has extras also... so 5.1 should work with eveything?

[andyp1]

From those I'd just keep the 5.1.

[j123vt_99]

also the compression level between using just 5.1 and all 3 is 62% to 67%.. is there really much difference?

[andyp1]

You may as well have less compression if you can . Would you really change between soundtracks if they were there?

[j123vt_99]

no.. but i also want to be sure that my dvd allows me to listen to ALL the features.. i'll try just 5.1 when i get home///thanks

[j123vt_99]

also.. why are there 2 audo files of the same type (2-ch)?

[Headbanger's Ball]

Might be one 2-ch for the movie and another 2-ch for Director's Comments.

btw. thanks everyone for the help... so could the extras be in 2 channel?? if so, by not choosing it and choosing 5 channel would i be losing out on it.. or is that just wrong?

If you look at the sizes, the first 2ch track is the longest, since it is larger than the rest.

The 5.1 channel is the shortest. Since 5.1 uses a higher bitrate, it would be a larger file than the others, but since it's rather small, it's a shorter audio file.

The last 2ch audio file is not the same length as the first.

This is most likely a multi PGC title set, in which each PGC has it's own audio clip.

In DVD Shrink, click on each title, and it will tell you which audio track corrisponds with that title (0x80,0x81,0x82).

Keep all of the audio tracks (in this case) to be on the safe side.

Had this not been a multi PGC title, just keeping the 5.1 would be good enough for most people.

Also, take a look at the audio setup menu. This will tell you which audio options are available for the main movie.
