I bought Sony LCD TV model KLV-32EX400 20 days back. I found that USB is not playing with full screen even after conversion of video file into MPEG2. The conversion of vedio file is taking 10 hour for one movie. They are not supporting simple DVD file.So, no use of USB with LCD. Do not look for this feature. Also, picture quality is not good. you can not see real picture of human.
I called many time and sent message to Sony service centre but they not solving my problem. Go for LG or samsung. I bought Sony because my wife is crazy of Sony.
