What are the .ts files you talk of? Movies have to be in one of the more known formats like Mp4, mv. avi or Mkv. The naming of the files need to follow what ever is on say JavLibrary and usually follow a 3 or 4 letter code and the a - and a 3 digit code as in VICD-051. You can add wording in brackets after but Javluv will ignore it but display all the same. The scraper Javluv uses just Parses the website for the DVD code much like when you search in Jav library and as the name implies, it scrapes up all the info and downloads it along with cover art to the folder where the movie is located. The info files or scraped info is in .nfo format which is used by a lot of other programs like Kodi if im not mistaken. If im wrong on any then im sure TmpGuy can clarify.
Enter some of your codes on Javlibrary and see if they are found, it they are then Javluv should find them just fine. If it does'nt then I would presume that your install and or APPDATA, data, is corrupt and may need to remove that and reinstall Javluv.
Just looked up .ts files. Never seen them before tbh and I bet Javluv cant detect them but for that you will need the man himself to answer you
Note also: Javluv will only work on JAV. forget it on everything else unless you do it all manual.
You could download AviDemux and see if it will do a Package flip or just load them in, select MKV and see if they will save. If not and you get an error then set the audio to AAC and 224 or something (Higher better in most cases) and then try resaving. If that fails then you may have to re-encode it with say x264 or 265.
