Sorry if I'm being dim, but why on earth would anyone want to be reminded that something is being recorded? Surely you would want to be reminded to watch something you're NOT recording...
I've never understood the Record and Remind feature and have never used it.
Because people kept moaning that there was no reminder feature (despite it just being a left over from the days when Sky boxes couldn't record), so VM added it.
I would say why would you want to set a reminder for something but not also set it to record, then it doesn't matter if you're not in front of the TV when the programme starts as it will still be recorded for you to watch when you want, not when it happens to be on. I guess the only use of reminders is if there's something you really want to watch live (sporting event etc.) but other than that just setting recordings seems far more sensible.
