I would love to say that DVD has a place in my heart, if only for the HD vids I can burn to them.. but I really cant.
Cheap manufacturers in EVERY sector have jaded me ~ whether made by vivid or burnt to a DVD-R I got from the local tech shop, I really havent had much luck. Bit-rot is real, and I find discs to be less permanent than I would like.
Granted the 10 years or so that I have burnt discs is plenty of time to upgrade to the next level and copy over... e.g. I copied all my floppies to CD back in the day, CD to DVD, bluray, so on, so forth.
Like you said, tho... scratched discs are a big concern. Heat warp, cold brittleness, bit rot over time, or just burnt badly the first time and the program didnt consider it bad enough to scrap the whole session.
Flash drives, SD cards, even hard drives arent much better.
Not that I expect the tech to last forever, but everything is still pretty fragile.. so.. I guess I vote for convenience over ownership ~ digital, plz.
