JVC DVD Recorder convert DVD-R to DVD+R

Who has experience with converting DVD-R that I get by burning DVD’s with my JVC DVD recorder (2005) to a DVD format that can be played also on my pc (DVD+R drive) and on my Pioneer CD/DVD player (2002)?
Do I have to convert these DVD’s or can the DVD recorder be preset so that it can burn another type of DVD?

Welcome to the CDFreaks;

You really don’t need to convert your burnt DVD-R to + R to be able to play it in your pc or any stand alone DVD recorder. The DVD-R is always compatable with any PC and stand alone also.
