Lately my tivo will not record any show that is 3 hours which mainly applies to sporting events. This is becoming very annoying as I am missing all of the stanley cup final games. Essentially I set it to record, it starts, then freezes anywhere from 15 minutes to hour later. The tivo still says its recording but it really is not. All of my other tv shows (30 mins, 1 hour, 2 hours) record just fine. I have tried resetting the device and deleting other programs to make space (even though I am pretty sure that is not the problem) but nothing works. Any suggestions?
