Ok, here's the situation: Recording of a concert, LTC comes from a HDW, 
audio hardware is synced to the video. The multitrack record is then 
mixed and mastered out of house. The easiest way I could think of to 
survive all the steps and the different systems involved would be 
recording the timecode as audio track. But I'm open to suggestions :)

Having the timecode track would also allow me to add the timecode meta 
information later on, since it is exactly the same information that 
would have been used to generate the timecode in the first place. I 
don't see why that should be a stupid idea. And I wouldn't have to deal 
with offsets or anything like that since I can identify the frame start 
with sample accuracy.

Yes, but to know the starting point I'd have to decode the timecode 
track. I could do this by watching at the waveform, of course...

Machines can do the work, so people have time to think.
