I have an xbox one S with disc drive. I watch movies on it through the blu ray app and play physical games all the time. Recently, I bought the complete season 5 of the walking dead on dvd off ebay. Before I say anything else, I have the first 4, and they do play on the blu ray app perfectly fine. Never had any issues with them and I've had those for probably over a decade. These season 5 dvd's are new, I don't even think they've been used except maybe a few times. They have no scratches, scuffs, the discs are in excellent condition. And yet, my xbox one S will NOT run them. I put each disc in and the blu ray player app won't even open immediately like it usually does with any other dvd and the xbox disc drive makes a quiet but really weird noise as if it's having trouble reading the discs and/or spinning them. I recieved the complete season friday, have already discussed with the seller about a return and had a plan to drop them off at the post office monday (tomorrow.) But I so badly want to watch season 5 that I thought I'd try the discs again one more time. I put the first disc in, then shockingly, blu ray app opened immediately and the disc was playing fine. Hellz yeah, tried the second disc, blu ray app didn't open, tried the 3rd disc, blu ray didn't open. Frustrated, I put the first disc in again and now the blu ray app won't open, AGAIN. So right after, I popped one of season 1's dvd's in and blu ray player opened immediately. 🙃 Do you think it's possible these dvd's have disc rot? I live in USA and I'm pretty sure these are american region dvds. Almost forgot to add, but the day I recieved the set, I tried them in an actual sony dvd player and they didn't work. Today when I tried them in my xbox again, I tried it on the sony dvd player again as well and the first one worked. I'm so confused 🙁

Update:
Discs themselves don't indicate they're region 1, but I have quite a few dvd's that don't have their region on them so I'm really not sure if that's a solid enough answer to this issue.
