I have RecordNow DX 4.60 installed on my PC, I had been using it with my LiteOn LDW-851S. After installing the PX-716A, RecordNow doesn't 'see' the Plextor.
I also have, but have never installed, RecordNow 7.3 LE & MyDVD 5.3 LE, which are on a CD that came with my Dell laptop.
I also have, but have never installed, RecordNow 6.5.1, which is on my Backup MyPC CD.
The reason I don't just go ahead and install the Roxio Easy Media Creator 7 Basic that came with the drive is that I had lots of trouble with ECDC 5.0 Platinum. Never have I paid so much for so much grief. RecordNow DX 4.60 has been solid as a rock.
Thanks in advance for your advice.
