I subscribe to LoveFilm and I have to say was pretty disappointed when they switched from Flash to Silverlight. Mainly because I can no longer stream movies with Linux, but also because I have had problems with Silverlight before. I wasn’t surprised therefore that when they made the switch my media computer stopped streaming films. I tried all the normal stuff, turned off the firewall, added *.lovefilm.com to the trusted website in the control panel. Uninstalled, reinstalled. Tried different browsers, cleared browser cache. Everything. Nothing worked. I even contacted LoveFilm support who asked me to do all that again and then pretty much gave up.
I then noticed that it was only DRM content that wasn’t working! Annoying, as I should have spotted that before. So some more digging and I found that the DRM licenses used by MS software are stored in “C:\ProgramData\Microsoft\PlayReady\mspr.hds”. So I renamed it. Bingo, DRM content including LoveFilm streaming now works! Doing this will mean you loose all existing DRM licenses, for me that wasn’t an issue as I didn’t have any. Frustrating! At least I can stream films now. Well, just need to encourage my ADSL modem to find enough bandwidth, it over heats poor thing and gets all slow and rubbish.
Same problem here. I have read that the MSPR.HDS file gets corrupted when you upgrade from silverlight 3 to 4 . Very frustrating and Lovefilm support offered no help what so ever.
