TDI 300 seat mounts for dvd screens

Hi, has anyone had any experience with fitting dvd screens to the rear of the headrests ? I have researched in most shops & people out there don't seem to know if there is anything out there, surely someone has done some sort of a modification to make the brackets fit, Halfords have said to strap them on with ratchet straps but that's seems a bit excessive to me.
Velcro straps were another option but the dedicated screens that come with the Velcro straps have very poor reviews. The system I am looking at is the Halfords | Nextbase Car 7 Dual- 7" Dual Portable In-Car DVD Players

Thank you
