For instance a recent one is my Survivor recordings. It has the season and episode info from the first episode last week. But the episode from this week is missing that info.
So to get plex to properly place the episode I need to manually add the season and episode info into the file name.

Make sure your tivo username & password are configured correctly in kmttg too. If you have multiple Tivos, the RPC enable option is configured on a per Tivo basis.
The quality of Tivo metadata is declining. The CW network is wrong more times than it's right for primetime season & episode information. Most of the other networks in primetime have had correct metadata for me during primetime for the new fall season. I do expect the quality to decline as Tivo misses new episodes and their episode numbers diverge. I have given up reporting lineup errors to Tivo.
