A lot of people are having problems recording to their NetMD.
If you are having recording errors(50% thru SB or about 89% or 0% in RealOne), and it is independent of which program you use, RealOne or Simple Burner, your most likely solution is outlined on this website: http://sas.seb.free.fr/
You will also find the files siteicv.dat and maclist.dat hosted on the site.
And people, please don't recommend formatting your hard drive as the solution to a NetMD recording problem unless the person has a boot sector virus.
If someone could put this restore file procedure in some type of FAQ or sticky, I believe that would be really helpful.
