I have just bought a UE40MU6100 and I've noticed that the iplayer app won't fast forward or rewind. It's really annoying. I've contacted support to raise the issue and done the usual resets etc but still no luck. Does anyone else have his problem or has anyone come across a solution to it? Thanks.
I have a new MU6020 that had this issue too. It was on software vers 1147 I think, and it didn't see any newer version when asked to search for an update. On Samsung's support page for the model, however, you can download version 1151 and install onto the TV with a USB flash drive. The download is an exe that extracts a disk image to the flash drive, so you'll need a Windows PC to hand. This has fixed iPlayer for me.
I guess that an update will be rolled out to the TVs in due course. Good luck!
