Writing backups to optical media may be unwise
I went through a TV-watching phase about ten to fifteen years ago, and I wrote 300 DVD-Rs. The first few were done on a tower PC with Pinnacle, and the rest were done on a DVD recorder - a Panasonic DMR-E85H.
Lately, a friend, wanting someone to trailblaze the process for him, talked me into ripping the collection to my NAS, and I went through those off-air DVDs with MakeMKV and VLC Player.
Approximately 10 percent of them ripped perfectly. I got something off another 8 percent. The rest had become unreadable, despite being held in light-tight boxes with sandal-wearing organic tofu sleeves which were specially designed not to degrade DVDs.
Many of the unreadable DVDs looked absolutely pristine.
So owners of home-recorded optical media are advised to get cracking and back up their home-recorded DVDs to hard disk before they evaporate.
I do not regret the loss of the recorded material. I'm over TV nowadays and I don't have a telly. Anyone who wants to deliver propaganda and subliminal assumptions to my home can put pen to paper and buy a postage stamp. I have a cross-cut shredder and I'm not afraid to use it.
