Your Nero software includes certain features that require the activation of a third party patent. The activation of these patents is easy and free of charge. If you choose to activate the patent at a later time, you can still use the respective features, but you will receive periodic reminders that activation needs to occur within 30 days of your initial use of the product. After this 30-day period you must activate the patent technology before you can continue using the corresponding features.

In some cases our servers could be down, or we may have an unusual amount of traffic on our website at the time you have attempted a download. In these instances, all you need to do is try again at a later time that same day. If it's over the weekend and the server is down, wait till the following Monday and we will have the problem resolved. We do provide up to 6 servers to download from. It's unlikely all 6 are down at the same time.
In most cases, the problem is not at our end of the connection. To resolve issues at your end, you should do the following:
- Disable any anti-virus program, Norton Protection or similar programs.
- If you are at work, you may need to approach your IT administrator, as you may have a firewall preventing such downloads.
- Contact your Internet Service Provider.
- Try downloading from another computer.
- Any kind of popup blocker could also cause problems. Please disable them while you download.

Unfortunately, your license for Nero only allows you to use the Nero suite on one PC at a time. This message most likely indicates that you are attempting to use your Nero-licensed product on more than one PC. Please follow the dialog box in the activation window in order to obtain an additional license for your Nero software at a special discount price.

Nero Digital is a Codec. Basically the Codec adopts the MPEG-4 standard but has some extensions, e.g. Subtitles, chapter creation, 2 Audio-streams and navigation (soon). It is our reaction to the MPEG-4 Standards but it is 100 % standard compliant, including MPEG-4 Part 10, AVC [Advanced Video Coding or H.264]. According to this, it is a perfect position to use the vantages of the HD Technologie of the next generation, including HD-DVD, Blu-ray, VOD and HD broadcasting. It contains MPEG-4 ASP (Advanced Simple Profile) video as well, like DivX and Apple; MPEG-4 AAC audio like iTunes and 3GP mobile; using the MP4 file container. Compared to the DivX format which uses its own containers, the Codec is technologicaly seen very free – equally opposed to Microsoft, Real and Apple with its own DRM (Digital Rights Management) extensions. In principle, files created with Nero Digital are supported by a wide range of Hardware and Software if the MPEG-4 standard was followed. That is why Nero Digital does extremely fit to the future, especially if you consider that both HD-DVD and Blu-ray together with VC-1 [Windows Media 9] have adopted AVC as obligatory Codecs for the next DVD-Generation.
