After update to 17.1 in mysql library the recordings state (seen etc.) is gone. Windows and Libreelec on rpi as well.
In updateted database the earlier played file is in files table strFilename:
“Doktor House House, M.D. orvos-sorozat , TV (PRIME), 20170404_120000.pvr”
In database all new played recordings general new row, and the strFilename characters coding problematic:
“Doktor%20House%20House%2c%20M.D.%20orvos-sorozat%20, TV%20(PRIME), 20170524_232500, 38266017.pvr”
