echel0n 0d9fbc1ad7 Welcome to our SickBeard-TVRage Edition ...
This version of SickBeard uses both TVDB and TVRage to search and gather it's series data from allowing you to now have access to and download shows that you couldn't before because of being locked into only what TheTVDB had to offer.

Also this edition is based off the code we used in our XEM editon so it does come with scene numbering support as well as all the other features our XEM edition has to offer.

Please before using this with your existing database (sickbeard.db) please make a backup copy of it and delete any other database files such as cache.db and failed.db if present, we HIGHLY recommend starting out with no database files at all to make this a fresh start but the choice is at your own risk!

Enjoy!

Parser of FastTrackerII Extended Module (XM) version 1.4
Documents:
- Modplug source code (file modplug/soundlib/Load_mod.cpp)
http://sourceforge.net/projects/modplug
- Dumb source code (files include/dumb.h and src/it/readmod.c
http://dumb.sf.net/
- Documents on "MOD" format on Wotsit
http://www.wotsit.org
Compressed formats (i.e. starting with "PP20" or having "PACK" as type
are not handled. Also NoiseTracker's NST modules aren't handled, although
it might be possible: no file format and 15 samples
