People should try CDBurnerXP (updated to work on 7 and 8 despite the name!) for a basic and reliable burner. It burns data, audio and ISO to CD, DVD and Blu-Ray. It also prints cd covers. It's very lightweight (the reason I've never been tempted back to bloated commercial products), and I've used it for years without having any errors burning or reading data years after. Note, if you wish to use it for disc spanning (ie: burning 20gig of photos to several DVDs without having to do each disc separately) simply add all your files to burn and click burn. You will see an option for spanning and can choose to either keep files together or use as few discs as possible. You can also choose to add a TOC for each disc (a text file) to print out and keep with your disc archive.
Oh and it's free!
