Nope...of course not. Multisession on DVD's is a Nero speciality/stupidity which is way out of OSTA specs. But if you use UDF 1.02 and TAO-open as burning mode the net result is the same, and the burned DVD's are compliant to any filesystem. In fact there is no reason at all to "need" multisession on DVD's, unless you mix up your needs on CD's.
