bought a couple of brand new 25 pack blank DVD-R and DVD+R discs......assumed that I could transfer mp3 files to these DVD-R and DVD+R discs and play them on a conventional CD player. Besides playing mp3 files on a DVD player (which is ok, but not my first choice), what are the best uses for these discs for a beginner level computer user?..........
Chscag has already provided you w/ most of the potential uses for your DVDs - the type , i.e. DVD-R & DVD+R should not make a difference, although in the early days some machines & media brands were finicky.
Keep in mind that a recordable single-sided DVD has 4.7 GB capacity, so 'backup' of photos, video & data would certainly be a good use; today, most use standard HDs or SSD media (drives, USB sticks, etc.).
As to music, a LOT of MP3 files could be stored on a DVDR - I've made CD-Rs w/ 6-8 hours of MP3 files (nice for the basement shop), so not sure if that is the best use, but if you want to archive your music in a 'lossless' format (including just burning CDA), then you could get a half dozen or more regular CDs onto a recordable DVD; and current disc players (whether DVD or BD) are backward compatible and cheap these days.
