FTP'ing to the T3

[tezza007]

I sent a 1388MB MPG to the T3 using FileZilla . It was showing over 700 minutes even though it's less than an hour long. I started playing it as it was still transferring and it went fine until the transfer was complete whereupon the screen went black. I stopped play, the file is still 1388GB, but zero time and now won't play, just a black screen

Any ideas?
