Curious for the Shows or Episodes I can't find on zap2it where to get the TMS ID's.
Does your Gracenote/TMS API allow you to discover those not found on zap2it?
Myself, I've been capturing the SHow and EPisode ID's lately (been adding them to the MCEBUDDY json metadata) as it seems even some recently recorded things can't be found with a search on zap2it.
I have recordings made years ago on TiVo's (when they used gracenote) that have the gracenote/tms id's in the recording metadata extracted with kmttg, but searching zap2it for those shows yields no results.
