I too had this a short while back (about 2 weekends ago?). I don't normally use wishlists but was mucking around one night and changed my Enterprise season pass for a wishlist, thinking I might start to use wishlists routinely after I recall someone mentioning they preferred them over season passes. I didn't notice until I'd missed a recording and then promptly changed back to the season pass.

I didn't think anything more of it, as soon after that I completely trashed my tivo (terminal freeze during reboot, no telnet or serial access) while hacking a script to auto grab shows off tivo in the wee hours, ftp them to a server and then have the server xvid encode them to mpeg4 for later viewing anywhere around the house on PCs or back on my XBMC capable XBox (I've been doing this manually for ages). My agricultural first attempt at bash scripting an ftp-based deletion of the show (via msf_ftp) after a successful download apparently had inintended consequences ...

Have rebuilt tivo with the new oztivo image and all is apparently well, tho' haven't yet gone back to explore the wishlist thing ... haven't given up on the backgrounded grab/encode thing yet (next attempt will more cautiously use an expect script) and will share my experiences later for anyone that's interested. I'd be interested if anyone else is modded XBoxing ...
