Well this is something that is really open to opinion im sure but I wanna know what everyone thinks. Recordable optical storage degrades, some more than others depending on quality. At what point do you consider the old burn garbage and reburn it to keep your data/movies safe?
What do you used to test your media and what level does it have to reach for you to want to reburn to keep from losing data? (I.E. scan a burned disc in cddvd speed that you made a year or 2 ago, and decide you should reburn it because it has xxxpifs, or because of xxx pies, xxx jitter, etc. Maybe a scan in kprobe, however)
What is your personal deciding factor?
What do you look for first that sets it in stone to you (besides the obvious crc errors or set top boxes refusing to play)
Do you have different deciding factors for movies/data?
Why do I ask? I see alot of varying opinions from reading/searching and im finding now that media I burned on years ago was very poor quality, I dont wanna reburn everything if I can help it so I wanna average out what other people consider too much as my starting point.
