Hello. I connected a Toshiba 320GB USB HDD to my KLD-22. I formated the drive on a HP Win7/64 machine to exFAT format with 256 sector size. It does play most video files in mp4 and avi up to 1 GB but won't play any file larger then 1 GB. The screen shows "Playback not available" I though of different dialects on mp4, avi, .. and tried different converters (format factory, ...). Butall the same. 1 GB seems to be the sound barrier for my telly. I connected the telly to the internet and it downloaded the latest version of the firmware. Still the same. Hardware defect? (Still under warranty)
