I have been having an issue the past few days where some of the latest BBC programs are not playing any more, presumably due to changes in the iPlayer site. I have been trying to reverse engineer a version of the new iPlayer flash player to enable auto play and full screen from the remote, but without much success (the player keeps freezing). As an interim measure, there is a version which displays the program using the new bbc player, but this requires use of the mouse;
If you are also having this problem, download and install that version, and use the mouse for now to press full screen and play. I am working on a way to resolve the issue.
