I would move the files into the directory structure and re-name any that have 1900 or 1899
For info - earlier this year we stopped auto matching recordings to thetvdb because the mismatching was leading to loss of recordings or getting repeat recordings - that was announced here EPG metadata is now retained for DVR recordings - With dedicated DVR libraries and no shows previously matched to thetvdb in those DVR recording libraries, the EPG metadata would then be preserved.
