Recently I have been getting the following message when I try to use BBC i player.
Internet download failed because size exceeded system memory unit.Not only can I not watch iplayer but it seems slow to load and getting from the Home icon to the category icon seems to take longer than it should.I can watch iplayer on my you view box and on my Amazon fire stick without any problem.The TV is a SONY KDL-42W653A.

Any help appreciated
