I have been using blank DVD+R discs to record movies. Someone gave me a pack of DVD-R discs. My recorder, player can handle both but what is the basic difference?

From Good Ol' Wikipedia!
The DVD+R format is divergent from the DVD-R format. Hybrid drives that can handle both, often labeled "DVD±RW", are very popular since there is not a single standard for recordable DVDs. There are a number of significant technical differences between the "dash" (it's not a minus symbol) and the "plus" format, although most users would not notice the difference. One example is the DVD+R style ADIP (ADdress In Pregroove) system of tracking and speed control being less susceptible to interference and error which makes the ADIP system more accurate at higher speeds than the LPP (Land Pre Pit) system used by DVD-R. In addition, DVD+R(W) has a more robust error management system than DVD-R(W), allowing for more accurate burning to media independent of the quality of the media. Additional session linking methods are more accurate with DVD+R(W) versus DVD-R(W), resulting in fewer damaged or unusable discs due to buffer under-run and multi-session disks with fewer PI/PO errors.

Thank you for that very informative reply. I always seem to forget Wikipedia

the only practical difference you're likely to come across is when and if you burn discs and give them to someone else to play - a lot of older dvd players only supported one or the other.
