Same issue here. It looks like the codec we use impacts the frequency of the error.
1080ps23.98 Prores 422 (HQ) with HDCAM Deck and Kona 3 is flawless but as soon as we do upconversions from Digibeta to 1080i 29.97 Prores (HQ)the error shows up.
It also seems to happen less frequently when we capture a clip at a time. Batch capture of multiple clips is impossible.
