If for media (music / video) use DVD+R and if data or games you can use DVD-R.

Just read the details from Stud post and you will understand clearly.

it's all about formats and how the data is being written. for compatibility's sake especially if you have older dvd players, use DVD-R disks. and read your hardware details carefully as to which format is supported to avoid getting a lot of coasters.

with today devices the only difference is that you can write on DVD+R faster than DVD-R.

today more than 90% of devices (and all of the famous brands) work with both format.
and DVD+r is a little (unnoticeable) more expensive .
