Nero & different dvd burning modes

[ljp]

What's the difference between udf/iso, iso and video modes in nero ? Some say that these modes affect e.g. compatibly issues. Is that BS or .. ?

"DVD-Video" mode (a subset of "UDF/ISO") was created SPECIFICALLY for the proper (automatic) handling of burning Video DVDs.

The other modes may be used, but no assurances of proper underlying settings.
