Gave it a lot of thought and went back and started recapturing the home movie tapes from scratch via lossless
Tried Vdub first but always ran into heavy sync issues (there would be dozens of frame drops in the first 10 seconds).
Used AmarecTV instead with LAGS. File appeared to be OK... but there was a moment when the picture froze and the audio kept going, but still managed to be in sync.
The end plan for these videos are going to be computer/file viewing, no real intention for DVD or BD. But any time I process the video stream, that freeze spot creates an audio desync for the rest of the video length. Last night I tried Avisynth and QTGMC for the first time... looked beautiful, smooth and deinterlaced, but the audio was mismatched at that spot in the new file.
Is there anything I could differently during initial capture to prevent glitch spots like this? Or is this a TBC only fix. I attached the segment of the video when it visibly freezes then jumps ahead.

All that aside, now I really understand the errors of my ways when comparing the 5Mbps m2ts capture to the lossless one I just made last night, all that ugly color noise gone.
