Look at what the reviews cover.
They are reviewing Burning ROM not the Nero Suite.
While N.B.R. can be purchased separately, it is only part of what is in the complete suite of burning apps.
Nero Burning ROM is knocked down because it does not deal with video formats:
NTSC, PAL, WMV, and so on.
This is not a fair comparison between apps of similar or same capabilities.
The Nero Suite should have been the one to compare to the others.
