Vangelis, you've hit the nail on the head, the issue is caused by a 
corrupt FLV file which of course results in a corrupt mp4 file (garbage 
in, garbage out)

And for me too and as for the OP it occurs only for large files.

Once again, you're a star, Vangelis, not only did a programme of 4 hr 13 
min take MUCH less time to download than using RTMP but the download was 
faultless!

Brill stuff! Your cyber-medal is in the post! ;-)
