My search of the tivo support webpages found the following statement: "If Keep Until is set to Keep Until I Delete, all episodes recorded will be kept until the Keep at Most limit is reached. For example, if Keep at Most is set to three episodes and Keep Until is set to Keep Until I Delete, recording will stop after three episodes until you delete one or more of the episodes." This is exactly what I want my Tivo Premiere XL to do for many programs. However, when I set the Season Pass options for a program to these settings, my Tivo continues to record and keep episodes after reaching the "Keep at Most" limit (without deleting older recordings). I am trying to utilize the limited HD space to record fewer episodes of more shows. Please help!
