Default Archiving to DVD

Are you talking about uncompressed formats or compressed formats like
wma
or mp3?


Archiving standard audio files at 24/94 resolution is my main concern.
This would be in aiff or wav type formats.

Having browsed the Pioneer FAQ it states that wav and mp3 files can be
read from DVDs. This was not my interpretation of the manual. I think I
need to sacrifice a few more DVDs to check I have not made a mistake
with my first attempt.

DVD video is a delivery format, not a computer storage format - and

is
likely to be around much longer than DVD-Audio which will turn into a
curiosity - just like SQ, QS or CD-4 from the 70's.


DVD-Video and DVD-Audio are a bunch of files on a filesystem. They are
not like an Audio CD but more like a Data CD. However, there is, I
believe, a requirement for the contents of some of the files to be
stored sequentially on the disk and so one could argue for somewhere in
between.

DVD-Audio is an extension to DVD-Video which requires better D-A
hardware but this is becoming fairly cheap. My guess is that in a year
or two all new DVD players will support DVD-Audio with the possible
exception of the very cheapest because the cost to include it will be
very small and the impact on sales of not having that box ticked is
likely to be not small.

Unfortunately, this still means a lot of DVD hardware around will not
play DVD-Audio.

If you want something better than CD that is widely playable then DVD


video is the best way to go.


Agreed. 24/96 is supported as the highest resolution but players that
cannot meet this are allowed to drop the resolution.

DVD video should be even simpler than DVD audio - there are plenty

more
tools that support it so I'm not sure what the problem is. But then

we
could be talking about completely different things. I'm not sure if

what
you are calling DVD audio is really a standards compliant DVD-A disc

or
just a DVD-ROM with audio files on it - there is a very big

difference
between the two.


The problem is that I am principally archiving audio file which I would
want to extract and process again as audio files at a future date. The
ability to play them in home DVD players is certainly desirable but is
not the main objective.

My original problem was that creating a DVD with a UDF file system
containing audio files in WAV format did not play on the DVD player.
However, creating a DVD with a UDF file system and arranging the files
and their formats to conform with DVD-Audio did produce a playable DVD.

I am newish to DVDs so I had to look up DVD-ROM. Assuming DVD-Audio
means the files in the AUDIO_TS directory and DVD-Video means the files
in the VIDEO_TS and DVD-ROM simply means other files on the disc then I
would ideally like a DVD-ROM with audio files on it to work.
