What *IS* "DVD High Compatibility Mode" in Nero?

[tbessie]

I have not been able to find any documentation (both in Nero, on their site, or here) as to what "DVD High Compatibility Mode" actually *is*.

Can someone here tell me?

I believe it simply adds null data to your project if it is below a certain size. Apparantly some DVD players have problems reading DVDs with only a small amount of content on it, or so Nero says. I've never heard of this actually happening.

Thanks, Adam! I hate features that go completely undocumented.
But then, Nero *is* a kinda weird product.

I made some 15min. DVDs for a client that didn't work for him, even though they worked fine for me After researching the matter, I discovered that DVDs are supposed to contain at least 1GB of info (even if some it is useless stuff in an extra folder). So I remade the DVDs with 1GB+ and they worked just fine. Apparently its part of the DVD specs, but most players seem to do okay anyway...

I read somewhere it's for DVD+R/RW only.Then in Nero 5.5 the box said "for certain players such as XBox",in Nero 6 there's no mention of Xbox.
In my experience it does nothing but write a longer lead-out,the file size is the same with or without it enabled.

Yes. There is a dokumentation inside the Nero SDK:

dvd_high_compatibility: Used for better compatibility of burned DVDs as
at least 1GB will be written.

dvd_high_compatibility: Used for better compatibility of burned DVDs as
at least 1GB will be written.

This limitation (1GB) is no longer required in new drives. See the section "Lift off of 1GB Limitation" in the link below.
