Forgetting about HD and bluray, which recordable DVD format is the
best?

The reason I ask is I was backing up some old tapes onto DVD for my
brother, and he gave me a spindle of DVD+R discs. Previously I have
used only DVD-R discs for recordings that I want to write once and
finalise into DVD-Video, and DVD-RAM for timeshifting before we got a
PVR.

Is one of the +R or -R better for any reason, or are they
interchangeable?

Apologies for my ignorance!


Cheers
