2000 P38 Autobiography - Rear video player: How to change?

I LOVE the fact that there is a video cassette player in my Rangie lol but apart from the fact that its a 2000 Autobiography and I'm sure DVD's were out then(!) I would like to change it for perhaps a DVD player or a digital Tv Tuner perhaps? i missed out on one on ebay so any suggestions folks?

hi a slimline ps2 fits perfect under rear seat and plays dvds in my vogue 50 i just connected a inverter and used the phono plugs with extension leads worked perfect no need for removal or chopping anything
