The thing to watch out for, both in logging and in capturing, is when you log or capture multiple tapes with mixed NDF & DF timecode.
There are three or four things that can affect this:
FCP5 and later allow you to set the TC format of the capture preset, such that the Log & Capture window would default to NDF if you are working with NDF tapes.
Otherwise, Log & Capture will still auto-detect during playback when logging, but you have to be sure to play the tape some before logging the clip. If you capture multiple tapes using capture now, You could easily start recording before the time code format updates. This kind of error results in a clip whose in point is the correct "number", but the format is wrong.
During Batch Capture, the device control is not always able to change the time code format. I'm not sure about FCP6, but I am in the habit of grouping my clips in batches according to the TC format. You ma be seeing this alert because you are switching the TC format of the tapes in the batch capture, but device control is "stuck" in DF mode, for instance. This is not an issue during logging, only capture.
I think it may also be possible to override the clip's logged TC format at capture by unchecking "use logged clip settings".
Capturing clips with the wrong TC format can really mess up recapture later. The offset that happens as the format gets converted back increases as the starting hour of the timecode gets bigger.
So basically you can have clips that get logged wrong, and clips that were logged correctly, but captured with the wrong TC. It's easier to miss it when logging, since there's no alert message to pop up. But the other alert is there to tell you there is a mismatch somewhere, preventing you from making the second kind of error. Your only error may only be that you had both DF and NDF clips in the same batch.
There is a trick to get the TC format to switch to the non-default for batch capture - Open Log & Capture and play the tape until you see the TC format update. Now start the batch capture with Log & Capture still open - device control will stay in that TC format now. Otherwise, I think device control switches to the format of the first clip in the batch, but stays there until you cancel and start a new batch.
