Why Does Lead-Out Take So Long For Small Data Writes?

[LisaB]

Sometimes I just want to write a few hundred megabytes of data to a DVD-RW as a test. I find, however, that my DVD writer (which does DVD-RW at 2x) still takes about 8 minutes to finish, with the vast majority of this time spent doing the leadout.

Now, I *think* that there is some kind of technical specification that says for maximum compatibility, you shouldn't write less than 1 Gb of data to a DVD, and so if you are only writing a 200 Mb data file, then the lead-out will have to be huge in order to make up for it...this would explain the phenomenon that I am seeing.

Can someone out there clarify this a bit. And if anyone knows how to disable this behavior in Nero, that would be great!

The 1GB rule was the way I understood it, also...

yep right

Ah Hah! Found it!

If you go to Recorder -> Choose Recorder, then click the "Options" button, there will be a checkbox for "DVD High Compatibility Mode"

I knew I had seen something like this before in some burning application....

You know, I saw some other posts in this forum from other people complaining about lead-out times....yet no one ever mentioned this...

I'm sure this will make a huge difference. I just burned 50 Mb to a DVD-RW (before I found the checkbox) and timed it -- it took 31 seconds to do the lead-in and write the data, but it took a little over 6 minutes to write the lead-out!

Using Nero Express, when you get to the "Final Burn Settings" screen where it lists the recorders available, there's an "Options" box next to it. Click that box, a window will pop up with a checkbox at the bottom which says: "DVD high compatibility mode (at least 1GB will be written)". I would assume if you uncheck that box then your problem should be solved.

Haven't figured out how to do it on the full version of Nero yet.

DVD high compatibility mode should always be used

I think I've seen this 'High Compatibility Mode' in B's Recorder before, too...
