It has been a while since I’ve used it, so I don’t remember which extension I typically use. However, on most extensions I have tried, the subs and [edit: dubs] subs are listed as separate series, and each season is listed as a separate series as well. So, a four season anime would have 8 different series listed for it. I know I haven’t tried Aniwatch specifically, but if you can’t find the (Sub) series on it then it may be worth installing another extension. As a side note, each extension takes up typically less than 100 KB or space, so there is not any downside as far as I know to downloading a few and trying them out.
I actually worked with a Leonard who preferred “Nard”
I’ve been ripping DVDs for several years now and have never seen this issue. What program did you use? I thought most retail DVDs were read only once shipped, so I am not sure how you could corrupt it.
Have you tried playing it in another player (like a recent game console or a Blu Ray player)? It could be a corrupted driver for your PC’s disc drive.
