I'd be absolutely furious if DD's nursery showed Toy Story. It's a PG rating, not a U. PG means PARENTAL guidance - and the rating states that it's suitable for children aged eight and over, and may not be suitable for younger children. I'd also throw a fit if they watched any 90-min film. If I'm going to pay £11 for DD to be occupied that way for 90 mins, I'll take her to the cinema myself.
DD does watch television for 15 minutes a day at nursery, whilst they clear away lunch tables and set up the nap area. I've no issue with that at all, but parents are informed of this when shown round the nursery, and the DVDs are available for parents to see/check - and they're all CBeebies stuff or Peppa Pig or whatever, i.e. U rating and entirely age-appropriate. We chose the nursery on the whole package - it was "like home" and if that includes a television alongside the Victorian house, the garden, the big squishy sofa and the manager who bears a remarkable resemblance to Grandma, that's fine. DD doesn't need to spend every minute of every day occupied in EYFS curriculum-specified activities.
I'd be pretty peed off about watching whilst eating though - part of the reason for sending DD is because she had major food issues due to severe reflux and I wanted her to see other kids eating normally. Maybe slightly hypocritically, on nursery days when she comes home she does have a snack and a cup of milk at her own little table in front of In the Night Garden; that's more to do with the late timing and the need to calm her down before bed. She wouldn't normally eat in front of the television though - food isn't allowed out of the kitchen at home.
So if I were you I would be asking how often they watch, and what they watch, but I don't think it's unreasonable for them to watch appropriate stuff for appropriate lengths of time (
