Panasonic DMR-ES20D (PAL) Turn Off TBC/Stabilizer?

Hi
I've got a Panasonic DMR-ES20D UK version and am using it to convert some old VHS tapes to DVD. I'm sure it has some kind of video stabilizer or TBC built into it as it fixes some old VHS tapes which didn't play well before, such as shaky video and wavey signal. Basically its good for some tapes, however there are a few tapes which I am trying to copy which play perfectly if connected to the TV but when connected to he DVD recorder, the built in stabilizer/tbc adds a jitter to the video which just kills your eyes when trying to watch it D:

So basically all I want to know is if there is any way I am able to turn off the tbc when its not needed as there is no option for it.

Thank You
