As noted, I tried that. The maximum time it will allow me to set on a record length in the "Limit Maximum Recording Time" option is precisely 3 hours, or as the error message says "10800 seconds." As noted, this provides a 1 seconds gap in between files, so when I go to join them back, it causes a gap in the joined file. Additionally, the same happens if I use the scheduler to create end-on-end schedules to record.
