Well I wasn't worried about Alan Titchmarsh as much as I was about that poor Charlie Dimmock. I sure hope she got a better job because with what they were paying her to be on "Ground Force", she couldn't even afford a respectable brassiere! Do you think the producers were aware of that???
(I would post a picture, but this is a "family friendly" forum!)
Using the beta application (I'm sure I downloaded it off the BBC iPlayer website when I first visited it on the iPad), the picture quality on my 27" LG LED 1080p screen is very very good, easily as good as Freeview. No problems with buffering either that seem to be plaguing the current app either.
If you're able to source the beta app, go for that instead.
