Unfortunately, it is a mov file;-((

The actual resolution is 480x576 (and you cannot change the input 
resolution for a mpeg2video stream), shown by both MPlayer and FFmpeg, 
the aspect ratio is 16/9 and is correctly recognised by FFmpeg, 
and is is encoded correctly if you choose avi, mov or mpegts as 
output format, it does not work correctly for mpeg program streams, 
you can use -vf scale though.
I cannot reproduce any corrupted frames with FFmpeg, please provide 
complete, uncut console output (either here or on ffmpeg-user).
