No disrespect intended but did you configure the deck TC settings correcctly? I can do assemble, inserts with frame accuracy onto D5 Decks no problem. If the TC settings are wrong then the deck will consistently edit in at the wrong point on the tape. I thought I was going mad, but had the luxury of 2 D5 decks to test with and it worked on the other one. The problem was traced back to a TC setting of 30 frames instead of 24 in the TC convert menu. This is with a Kona2, DVCPRO HD footage at 1080psf, 23.976.
