Merged: Yes

Changes
This PR will limit the series title to 250 bytes (so file extensions can be added). If the end result is longer, the title will be dropped and only series name is used with the timestamp.

This is an edge case where the XMLTV spec includes a sub-title. The spec guarantees that the title + sub-title is under 255 bytes (filename limit in Linux). However, since Jellyfin does try to add some descriptive metadata to the filename it can lead to exception.

Here is an example from a finnish cable provider Elisa
