My OS is Windows 7 and my Opera version is 34.0.2036.47. I was getting an error message about the Widevine Content Decryption Module and to go to opera://plugins and to make sure it was enabled - it was, so I tried clearing the browsing data and a few more things. I don't know what went wrong because it was working fine a couple of months ago.
Eventually I contacted Amazon Prime which was a complete waste of time. I didn't catch the man's name but he didn't seem to be able to grasp what my problem was even though I told him about the error message about the Widevine Content Decryption Module and that I was getting error 7235 so he kept me on hold for 5 minutes and then told me it was a problem with the Widevine Content Decryption Module, I pointed out that I'd already mentioned that. His "solution" was for me to use Google Chrome browser - I will not use any software by Google after my experiences with their Graphics Program; Picarso (I'll spare you all the details).
I was prepared to cancel my Amazon Prime subscription, mainly because they no longer support my Smart TV Box (It's a Samsung BD-D8500M - am I now supposed to throw it in the dustbin?). If I can't play the videos that I'm paying money for every month there's no point in continuing with it.
After some procrastination; I decided to uninstall Adobe Flash player then download it again and reinstall it. I rebooted, went back to Amazon Prime and did a quick check by watching the trailer to "The Great Gatsby" - and it played fine (it didn't previously).
I also had a problem with a video on Facebook; the video was there and the sound played through my PC speakers but not through the HDMI lead and on the TV's speakers but that now seems to have sorted itself out with reinstalling Adobe Flashplayer.
I still have a problem with getting the BBC's Radio Player to work - it worked in the past but not now (I hoped that reinstalling Adobe would have fixed it).
