My PC with DVD recorder came with Nero burning software. But every time you click you get messages telling you to upgrade, time to look for free burning software. Used CDBurnerXP Pro3 for a number of months but suddenly it did not want to burn anymore. Searching I stumbled upon HT Fireman CDDVD Burner. Tried this and first impression is very good (do not forget to click the DVD disc button on the first screen!).
