Anyone else having under-runs in the newer 5.5.2.4 Nero?

[Mike Zamarocy 1]

I was able to burn some CD's with no problems a few weeks ago with one of the older versions of Nero, but tonight I tried to burn some with the newer 5.5.2.4 and I made 2 coasters because of under-runs! My source drive is a Plextor UltraPlex 32, and my CDR is a Plextor PleXWriter 12/4/32 - both not cheap peices of junk.
