Problems recording onto 32gb USB stick on a KDL46EX723, its registered fine, when I record something the recording prematurely stops and I get an error message in the recording results, 'recording aborted as no registered HDD was connected', although in the title list menu I can find half recorded stuff, my question is has anyone got this function working correctly with this TV and a USB stick, Im thinking of getting a 64gb stick but dont want to waste my money if sticks dont work, cheers in advance.
