Imgburn is as good or better as a burning program.
AVStoDVD, VidCoder, Handbrake, BD Rebuilder, and DVD Rebuilder are all better conversion/compression programs for their respective formats.
I find Media Player Classic Home Cinema and PotPlayer are both excellent media players, with the exception that they have no support for Blu-ray menus. I prefer TMT 5 for that, but it is a commercial program, and no longer available. So I have no need for the Nero Player.
These are the programs I work with. Nero does offer video editing, but many video geeks prefer VirtualDub, Avisynth scripts and even AviDemux among the free choices. There is also AviUtl. There are several other commercial editing programs meant for the amateur, that I would recommend over Nero, including VideoRedo TV Suite, Sony Vegas Movie Studio and the TMPGEnc programs, depending on what you are working with.
Nero has branched out with their latest offering, and now have streaming, mobile apps, and cloud storage, but I am barely aware of these, so can't comment on their quality.
I've never trusted the all-in-one packages, of which Nero is a prime example. They are rarely very good at any one particular task. I'd rather use free software that outperforms them.
