I bought a spindle of blank DVDs from rima.com (the cheap 59 cent 1x blanks) and they worked great until I upgraded from DVDXCOPY 1.3.1 to 1.4.1. Now when I burn a DVD with it it always aborts and gives me a coaster. I uninstalled 1.4.1 and went back to 1.3.1 in the meantime, but it's a bit annoying. Plus, I don't see a changleog for the program anywhere. Aside from not working properly for me, I don't know if I'm missing anything worthwhile with 1.4.1.
