I hope this might help you.

“Pulldown output is not available in this model”
You digitized all your 24p source tapes at 59.94i (with pulldown). You need a deck like the HDW-F500 with the HKDV507D pulldown board installed. Here is some more info:

Without pulldown, the timecode and video coming out of the HDW-1800 will not be usable in a 59.94i project.
Using the HDW-F500 with pulldown you can convert video and timecode to 30i DF or NDF
You will need to set these menu items
Timecode Sense Select 24p/30i
Pulldown Control DF/NDF
This will match the way you digitized the J-H3.
You were swindled by your deck dealer. If you want a more knowledgeable dealer let me know.
