hello from pireaus guuyyyys. Yesterday I also bought the 42LB650V and I am here to join the disappointment group..... I own a previous 47'' (about 3 years old) model which made me very happy every single day and I still love it!
ALSO, a major issue with USB playback function is that the fastforward option reallyyyy suuuuucks BIG TIME. And the skip chapter option simply doens't exist when viewing a movie from usb/external hdd
I dont have the time nor the mood to dive deep in the specifics of the tv so there only two options for me:
either take it back to the stoe and replace it with a previous model
or..... plug my external hard disk to playstation and see everything from there until thy decide to make WebOs workable......
