create MDS or not ?

[jinjin_jp]

I always ise ImgBurn, Thanks very much.

I experienced strange thing.

I output files in Build Mode to HDD fat32, in setting of "create MDS files"="auto".
*When over 4GB, MDS was created.
*When under 4GB (422MB or 13.8MB), MDS was created, too.
But only when 4GB (1.52GB), MDS was not created.

What codition is whether MDS is created or not ?
MDS created when under 1GB ? (I remember to hear DVD-Video should be over 1GB.)

Regards.

When on 'Auto'.

< 1GB = Created.
Double layer = Created.
Multiple image file parts (due to file splitting) = Created.
Everything else = Not Created.


Well... that's how it 'should' work!

@LIGHTNING UK!

Thanks very much for the explanation.
I understand the feature of MDS "Auto".

I have a question.
Why MDS is need when "< 1GB" ?

Regards.

Because tools such as Daemon tools will see the ISO as a CD. If an MDS is created and mounted, the virtual drive is seen as a DVD. Try it and see.

@blutach
for the explanation.
I can confirm that DVDDecrypter shows "Disc Not DVD" when mounting ISO less than 1GB, and normally shows when mounting MDS less than 1GB.

Regards.
