Scotty - just a thought. I have 2 white boxes. My other box runs iplayer just fine.
The box I'm having problems with is the one I had Plex sideloaded onto. A friend showed me how to do it so I could listen to music files from my laptop in bed on my big old telly!
Now tv have just wiped plex from the box and apparently withdrawn the access to dev mode. I'm pretty sure that when the cheeky b*ggers snuck in and tampered with the box, they screwed up something within the iplayer app. Apparently, Plex is off the nowtv buddy list. I'm not going to go there - its an argument for proper geeks not pillocks like me.
I've tried factory reset, reinstalling, and all the usual gubbins. Still nowt, and still looking for a fix. Bottom line is, I think nowtv broke it.
I wonder, did you have something sideloaded?
