Why are you carrying out IVTC? Couldn't you just use force film in DGIndex?

What's your final intended format? If making AVCHD/BD then I think you'll have to add the black borders to the side to make the horizontal res up to 1280.

You can't use force film on titles like this, it was "scanned" in a telecine machine the same as 1993 star wars LD's were. This title was originally a laserdisc too. There'll be orphaned fields and changes in the pulldown pattern throughout. Having a quick look though, one time the pattern suddenly changes in-scene is at 16:10 where you can see 2:3:2:3:2:3 as normall and then suddenlty 3:4 (three interlaced frames followed by four progressive), evidence of video editing/splicing. It probably only happens half a dozen times or so, and so would be difficuilt to find more examples without going through every frame of film specifically looking. Generally, I never use Force Film if I know the source is "hard telecine" as opposed to "soft telecine".

My format will be x264, mkv. I only care about streaming from my PC to my TV, not about burning copies onto discs, if authoring AVCHD then all you need to do as you said is add the side borders at the end of the script before encode. Or, you could resize to 1280 x 768 (instead of 1200 x 720) and then crop 24 pixels from the top and 24 from the bottom to arrive at 16:9 (1.778:1).
