But they are officially released products which I have bought from stores which have a good reputation, Amazon among them. Not fron shady small shops on some backstreet.You might want to re-examine who you’re buying from. Seriously. Just because they sell them as being from Paramount, doesn’t mean they are.
Then, start checking equipment. A dirty laser or loose belt can lead to issues. Make sure the firmware is up to date.
My DVD player is working fine and as I've mentioned before, I have dVDs from the beginning of the 2000 which still works fine. My problems are only with those Star Trek series DVDs, except for the Voyager seasons I bought in 2006. They still works fine, even if I noticed a small glitch in the episode Tuvix some months ago..
Naturally the more you buy, the greater potential for problem-discs. Once in a while you just get a nasty TITLE. There was a Barbara Bouchet horror DVD called IN THE BELLY OF THE TARANTULA which I ordered two copies of...since both of them rattled my DVD player worse than the EXORCIST bed.
DVDs are best cleaned with outward motions rather than circular ones, with non-abrasive soft fabric. I avoid the plastic ''cleaners'' altogether.
Yes, but there's an unacceptable high percent of Star trek DVDs malfunctioning for me.
Not the sme problems at all with other series.
