When I had this problem, I used MPlayer options '-v -v' to find out the 
beginning of the buggy data. I think you can't use MPlayer to find the end. A 
(somewhat laborious) way to find the position where to combine the data 
(after downloading the missing part) is the clever use of 'cmp' and 'od' (or 
'hexdump' or 'xxd') and 'grep' or your favourite hexeditor.
