Ikr! It's crazy, just been reading this thread coz I have the same issue, exiting the app causes my ps3 to reboot and then I get file system check. NO OTHER APPS DO THIS (IPLAYER, NETFLIX, AMAZON INSTANT, ALL ON THE SAME PS3), IT IS NOT MY INTERNET CONNECTION, IT DOES NOT MAKE A DIFFERENCE WHETHER IT IS WIRED OR WIRELESS FOR THE APP CRASHING MY SYSTEM, DITTO WITH DELETING DATA OR REINSTALLING THE APP. Please reply with something useful, or at least admit your app is not fit for purpose. Could you imagine a PC program that blue screen of deathed your PC every time you closed it, and then the dev kept saying 'well, have your tried WiFi instead of Ethernet?' THE APP IS BROKEN! Some assurance that it is being fixed would be nice rather than these canned robotic useless replies.
