I have purchased 22" led ex42 model television of sony bravia company . They have given function to operate usb drive and watch movie or video through the device on tv . But they have not been given video file supporting for avi file format to open the any video in this format . Whereas I checked with others company tv model in that all file format are supporting frequently . I want to say sony company either they update software in all tv models including which has already sold otherwise I will return the tv and also complaint to consumer forum for same .
