Car DVD player / iPad mount

[KatyN]

After another horrific drive in the car I am convinced we want a telly thingy for our son in the car. However I'm really confused whether to go for a DVD player or an iPad mount.
Of course the iPad mount is way cheaper and we have films on our iPads that would be fine... But I'm unsure about feet kicking it! Also is there anyway I can control the iPad from the driver's seat?? It's not they I want to control what he watches but if something ends and he wants the next episode I don my think he could press the screen.. Because he can't reach but also isn't quite apple savy enough!

Nicely this decision is perfectly timed with his birthday and Christmas coming up!!
Thanks for any advice kxx
