Yeah I have the same problem with DumbHub and its driving me mad!
Its like unsolicited spam apart from the fact that I can't even opt out even though I have tried many times.
Don't bother doing a factory reset - out of desperation I done just that and now instead of downloading 9 crappy apps it downloads 11 that I do not want, have never downloaded and keep deleting.
It also deletes 3 apps that I do want, have downloaded and keep adding (including Samsungs very own 3D Preview app) and have downloaded and installed many, many times only to have them forcibly removed.
The Guide also seems to have changed taking me to a genre-type menu and needing another button press to get into the Guide proper although that might have come with the latest update or something.
I also get an intermittent channel preview in the top left window...sometimes it shows the program being watched when I am in the guide and sometimes it doesn't.
The above coupled with the extremely laggy remote when trying to browse through the FreeSat Channel Guide is affecting my sanity so much that I am thinking of ditching the bloody thing...not sure whether Richer Sounds would even consider a refund on this basis and the set being some months old now.
To add insult to injury when trying to use DumbHub it often fails & results in a message telling me there is interfernce on my Internet connection...this depite being wired with Cat6 to a Gigabit switch into a Gigabit router port connected to O2 up to 24MB service...granted I only see around 7MB of that due to the distance from the exchange but have bever experienced this so-called 'interference' on any other of the numerous internet-enabled devices in the house.
Was supposed to be getting BT Infinity today but BT didn't show...doesn't recognise my order number on their order tracking page and apparently they have me down for the 19th despite my paperwork clearly stating 15th...
Not having a great time when it comes to technology!
The Sammy looks lovely switched off and hanging on the wall though...
