Sorry for that glitch - it is NOT in the source, just in the final release...
Don't know why it happened, and why I have not spotted before release... it's a computer+human error, and I'm really sorry!
This could not be considered minor, and should be fixed ASAP; as I have to re-encode it, is there anything else that should be adjusted? Grain, brightness, contrast etc.?
Thanks in advance for your help!
