Bro this is a statement from ts official,
There is no difference in software between manual and auto updates... Manual updates are more likely forced updates which downloads the software whenever we want while auto updates are sent through broadcasters as and when they want... Even new box downloads the software on first start up and that can also be considered as manual updation...
So that can't be the issue... Its like that only... Actually its smooth but loading takes more time than earlier software, thats all i wanted to convey... Otherwise i am not facing any hanging issues...
