oops, I just found some info that may answer my question…
(before I found my answer…)
I just bought a LG 4167B USB External drive (yes, it is really an IDE in an enclosure…), and bought my first recordable DVD Discs. Up until now I used my still working Mitsumi CDR Burner I bought around 7 years ago. When I went to purchase the DVD’s (great sales at Frys) I asked what is the difference between -r and +r dvd discs. Which still left me confused. I ended up leaving with the -R type. I will mostly be using them for backup of different software, files, etc…
I have ran searches looking for info and did not find my answer on Yahoo or Google. I also searched here and did not find the answer.
A couple people said the one was for compatability with older drives, one was better for burning movies.
Any better info out there? Thank you.
