No MOV, no FLAC, MP4 no! The WD Support failure

I bought this equipment in June 2010. At that time I just wanted to MPEG2 video and MP3 audio playback, occasionally AVI container (with MPEG2 and MP3 or PCM audio). That was no problem.
Now I have 2011, MOV movies want to play, also MP4 videos and FLAC audio. According to the manual no problem, videos up to a size of 720x576 pixels to be played.
Since all MOV, MP4 and FLAC formats definitely not run with me, I have been in contact with the Western Digital support. After much back and forth I should each have a MP4 and a FLAC file to submit, to the media information produced by Media Info. I sent a small MP4 file from Youtube and a FLAC file from a separate CD, which formats were within the limits specified in the manual of the Media Player. The answer was simple: "The structure of the file and the combination of formats is not supported."

Since my AV Mini Media Player more promised in the manual formats will not play and the WD Support is simply to call failure, I rate the device with 1 star.
