fwiw, I upgraded from v2.01.86 to latest v2.03.20 over the air.
When I previously used BBC iPlayer with v2.02 firmware, the box always suffered from memory leak symptoms after quitting the app and attempting to play a video from USB drive.
Today using v2.03.20, I watched two short Youtube clips, then used BBC iPlayer to watch two recorded 30 minute programmes. I noticed the remote controls for the iplayer app became very sluggish/lagged when watching the second programme. When the programme finished and I quit it to return to WDTV main menu, the response of the remote controller returned to normal. Sadly, when I attempted to play a video from USB flash drive, a dialogue box popped up with the Low Memory message and advising to restart.
