As a trained Fernsetechniker I'd never get such problems, a device at the start. 1. The USB recording function goes smoothly only with certain hard drives. At first I had a WD Elements Portable External Hard Drive 1TB. Which has not made the greatest things reproducible. A recommended by Sony went without problems. You have to suck out everything from a deep directory structure branched from the Sony website, however. 2. The integrated IT media server is not 100% pure rabbit. Full HD videos more about 16GB are played via DLNA only when set on DLNA server the "Bravia" as TG100 manually. On my 2nd unit KDL 725 that is not necessary, therefore, to assign the TV device clearly. 3. The device is the complete User Interface lame as the oldest PC carrot. Alone when you turn on the device, it preceded by a minute can be changed to the program about. That's very annoying.
