I thought I'd share some snapshots of NTSC captures with and without the DMR-ES15 in the pipeline. These snapshots are from 1 NTSC VHS tape that was sourced directly from a CBC TV station (not over the air).
I captured them by stopping on the frame in VirtualDub 1.9.11 and doing Video > "Copy source frame to clipboard". Then pasted into MS paint and saved as a jpg.
My setup is pretty basic and on a budget. The two pipelines for these snapshots are:
1. JVC SVHS HR-S2913U > Pinnacle 710 USB > Windows 10 > Virtual Dub 1.9.11
2. JVC SVHS HR-S2913U > DMR-ES15 > Pinnacle 710 USB > Windows 10 > Virtual Dub 1.9.11
The ES15 is set with colour lighter/darker.
I'm a newbie, but by comparing them, I believe it shows how the DMR-ES15 corrects tearing, described by LordSmurf as "one of the harshest line timing issues that exists" (source).
The ES15 also affects the colour as it reduces the red/magenta in the shot. I am curious if this is a pro or a con.
Pro: Is it "removing or reducing chroma noise (the red/blue colored mist found in all VHS tape formats)" as described in the TBC FAQ on Line TBCs? Or if
Con: Is a bad side effect as described here: http://www.digitalfaq.com/forum/video-capture/11643-camcorder-line-tbc.html#ixzz7BLqLo4Hb
Snapshots show first without ES15 and then with ES15 (as per filename). I've also attached them as a zip file.

The ES15 clearly removed the flagging (aka wobbling, tearing) and the rainbows (what you referred to as color issue) thanks to reducing luma/chroma crosstalk by its internal 3D comb filter.
If you think the colors without the ES15 are more accurate you can easily adjust ES15 caps by increasing the saturation by about 15 percent with the capture device's video proc amp before capturing.
more extreme horizontal error at the top of the screen. Your screenshots show correction of typical waviness.
