I'm not sure if this is in the right section, but here goes... Recently I've had an iTunes authorisation bug appear. iTunes has started insisting my computer is not authorised to play my purchased TV shows or movies. Entering my password makes the system think two or more computers instead of one are authorised to play my purchased content. I repaired the anomaly once by using 'Deauthorise All' to remove the glitches, but it happened again, and 'Deauthorise All' is blocked until next year (WHY?!!). I only have one computer that I need authorised, and I hope the glitch doesn't cause me to breach my authorisation limit. If this isn't repaired, I may be tempted to use a DRM stripper program.
