“To TiVO” has entered the lexicon as a verb, meaning "to set one’s TiVO to seek out and record a given show. If one gets bored with a show, one can simply not watch it – a passive move – but if the show gets sufficiently bad one can specifically remove the show from the list – an active move. Has a word yet arisen for going to the trouble of preventing a show from being recorded in the first place?
To deTiVO?
To TiVOpit?
To TiVOtraSh?
I’d like to cast a vote for “to untivo,” dropping capital letters altogether.
To un-TiVO?
Unfortunately, using TiVO as a verb runs the risk of making “TiVO” lose its protected Trademark status.
1st reaction – do we care? 
2nd reaction – is there really a risk as long as the verb usage is only employed in connection with true Tivo hardware?? (which was the case in the original post.) I think you’re only in danger of losing trademark when some form of the word, (noun, verb, adjective) starts getting used in connection with the competition and imitations. 
Douglas Adams might have called it Tiverton, Tividale or Tivington Knowle.
I, however, hereby coin the word (drum roll please) … tiveto.
Taa-daah!
(Works up to his best comic book guy voice.)
[CBG]I doubt Douglas Adams would have been so unimaginative!![/CBG]
Seriously though, I doubt he would have used place names that just happened to start with ‘tiv-’ for a verb… he’d probably go with something a little more functionally descriptive. Though kudos on finding so many.
Tiv-veto isn’t too bad.
Why not ViTo? At least in e-mails and print, it has immediate recognition, and takes advantage of the useful pun set up earlier.
Sorry to self-quote, but I had to tack this on…
We’re talking about a man who, in a single scene, coined such memorable words as:
floopily
globbered
vollued
flollop
flurbled
gupped
willomied
quirruled
glurried
wurfed
(The memorable swamp chapter of ‘life, the universe and everything.’) At least, I think most of those were original.
Tivoff?
