Hmmm... it appears that my crontab entries will restart the Tivo every night during the affected weeks, not just on Sunday. I didn't know that crontab schedule values are cumulative. Figured this out the hard way when my Tivo rebooted at 3:01 last night! Won't harm the functionality... it's just annoying. Oh, well. Later today I'll try to amend the logic (or edit the tcl script) to make sure this runs only on the Sundays.
