Please help - RecordNow 4.6 & px.dll error

[Hagar714]

Does anyone have (or know where I can get) RecordNow 4.5 or 4.6 ?? The disk that came with my LiteOn DVDRW seems to install but every time I try to use it I get the following error:

... program has performed an illegal operation & will be shut down.

I've searched for three days now & can't find an answer to this question, a copy of the px.dll (v2.0.60.500), or a copy of the prog.

Or - suggestions for software that will burn a DVD data disk (not make an image of & then burn a data disk) ??
