A script I use for renaming bulks of SRT files instead of doing them one-by-one. Put all 3 files in the same directory as the media files and srt files. The script should figure out and also propose before doing any changes, how to rename the SRT files. As long as they are in addic7ed (00x00) or subscene (S00E00) format, and episodes have S00E00 in their name.

Download the script HERE, PHP parser is included. MSDOS Batch based, if you have Linux you can just run the php files without parameters first to preview changes, and with "takeaction" as parameter afterwards. Listing of files included below.
