In the past, I've always backed up my data and applications to CDs. With the increased capacity of DVDs, I'm interested in getting a DVD writer. My concern is that I read all the reviews and see extensive discussions on PI/PIF errors. I don't remember a big focus on errors in CDR reviews in the past. A few errors in a movie probably wouldn't make much of a difference, but a few errors in an app or data file can make it unusable.
So are consumer-burned DVDs more prone to having errors than CDs?
